Q: For example, pulling straight out on a piece of taffy will stretch the taffy due to applied stress. For example, pushing on the middle of a tennis racket string will bend the string due to applied strain.
A: Note that material stress is caused by axial stretching force. Understand that material strain is caused by shearing force perpendicular to the axis of the material.

Q: Slide the safety washers over the axle and set them into place by pressing the tab on the washer into the tab hole on the dropouts. Thread the axle nuts on by hand, and then finish tightening them with either a wrench or ratchet and socket. To avoid a crooked wheel, tighten each nut a little at a time, as this will help keep the wheel centered. If you're installing pegs, make sure you do this before putting on the axle nuts. Pegs are short metal tubes that extend out from the wheel and act as foot holds for when you're doing tricks. It's best to start with the front wheel installation because this will help keep the bike balanced as you work. Slide the axle into the dropouts. Wrap the chain around the back sprocket first, followed by the front sprocket. Then, close the chain by: Butting the two ends of the chain together. Sliding a master link (the open-faced link that can be connected to attach the chain ends) through each chain end to join them. Pressing a plate around the two pins of the master link. Sliding the clip over top of the plate and snapping it into place. Use a flat-head screwdriver to snap it in place if necessary. Loosely install your pegs or axle nuts. Pull the wheel back to tighten the chain, and then tighten the pegs or axle nuts a little more (but not all the way). To make sure your chain isn't loose, start by tightening the non-drive side of the bike first (the side opposite the chain). Then: Straighten out the wheel and tighten the axle nut or peg on the drive side. Then, snug up each side evenly until the pegs or axle nuts are on properly. Once the wheels and chain are on, flip the bike back over again or take it off the bike stand. Loosen the bolts on the stem if necessary and adjust your handlebars so they're in a comfortable position. When you have the handlebars in the rights place, snug up the bolts in an X pattern. Tighten the compression bolt if the headset is loose. Make sure the stem and front tire are aligned before tightening your bolts.
A: Mount the front wheel on the fork.Set the front axle into the dropouts. Put on the back wheel. Install the chain. Tighten the chain. Adjust your handlebars and headset.

Q: Most outdoor speaker systems run off an existing indoor receiver. Since the receiver is a sensitive piece of electronics, you almost always want to set the receiver up indoors. A multi-zone receiver allows you to have music playing outside while something else plays inside. Make sure that it is in a sheltered location. You will be running the speaker wire from the receiver to the volume control box, and then from the volume control box to the associated speakers. Most volume control boxes can be easily mounted on an outdoor wall. Consider multiple volume control boxes for multiple pairs of speakers. This will allow you to control the volume across multiple zones. Each pair you add increases the chance of overloading the receiver's built-in amplifier. You can install the amplifier right next to the receiver and then run the speaker wire out of the amplifier. 16-gauge is fine for less than 80 feet (24 m), but longer wires should be 14- or 12-gauge. If you don't use the right gauge for your speakers, your audio quality will suffer. The longer the wire, the more degradation will occur. Four-conductor wire allows you to connect two pairs of speakers with one wire, potentially saving you the hassle of running a lot of wire. For outdoor speakers, CL2 and CL3 speaker wire complies with US in-wall standards, which means it can be safely ran through walls without causing issues with other electronics or posing a fire risk. This wire can also withstand elements, which is essential for an outdoor setup. Add an additional 10-15% to the length for snags and slack. You don't want your speaker wire to be pulled tight, as crimps in the wire can affect sound quality. Drill a hole low in the wall to run the speaker wire from the inside to the outside. Make sure to seal the hole with silicone to maintain your house's insulation. Run the speaker wire to the volume control box, and then run a second wire from the box to the speakers. Don't run speakers through windows or door jambs. This can cause your speaker wire to get crimped, causing audio issues. Some modern speaker setups are completely wireless, and operate using Bluetooth. If you are using a setup like this, you don't have to worry too much about wiring. You just need to ensure that your receiver supports Bluetooth speakers, and that the speakers are setup relatively close to the receiver. Bluetooth can reach about 150 feet (45.7m) if there is nothing impeding the signal. Walls between the receiver and speaker will shorten the effective range.
A: Set up the receiver indoors. Install a volume control box outside. Install a multi-channel amplifier if you are running multiple pairs of speakers. Obtain enough speaker wire. Run your speaker wire from the receiver to the outside area.

Q: Take hold of the loose edge of the backing and peel it off in one smooth motion. Try not to let your fingers make contact with the adhesive itself, or it could lose some of its stickiness. Your local sporting goods store may carry eye black stickers in the baseball or football section. If not, look for them online. A package of eye black stickers typically only costs $4-5, and often includes around 12 pairs of stickers. Hold the sticker over the flat part of your upper cheek just beneath your lower eyelid. Try to line it up with the middle of your pupil. Essentially, you want the sticker to sit between your lower eyelid, the point of your cheekbone, and the nearest nostril. Some eye black stickers are curved slightly to fit along the contour of the player's eye. If the stickers you're using are curved, arrange them so that the curve is pointed upwards like a smile. Take your time to double-check that each sticker is positioned correctly before you smooth it down. Once you've got your first sticker situated just right, touch it to your skin and apply light pressure for a few seconds. Then, smooth the sticker from end to end with the pad of your finger to make sure it's secure. There's no need to bear down too hardjust be sure that every part of the adhesive back is making contact with your skin. Remember to align the sticker with the center of your pupil about 1 inch (2.5cm) under your eye. Press the sticker to your face and run your finger over it to smooth it down. Both sides of your face should be congruent. Resist the urge to mess with your eye black stickers once you've got them where you want them. If they're not, carefully loosen them and adjust their placement as needed. Just avoid removing them too many times, or the adhesive will begin to wear off. One major advantage of eye black stickers is that they're much easier to remove than the stick. Just grab the edge of each sticker, pull them free, and toss them in the trash. Don't attempt to use the same stickers more than once. There's a good chance that they could come unstuck during a crucial part of the game.
A:
Remove the backing from the adhesive sticker. Center the sticker about 1 inch (2.5cm) below your eye. Press the sticker into place. Place a second sticker below your other eye. Look in a mirror to make sure both stickers are straight and level. Peel the stickers off when you're done playing.
