Students will almost always assume the nail joint will be the strongest. Another effective translation of physical science in agricultural mechanics was created by Dr. Phillip Buriak. Dr. Buriak developed an outstanding exercise in the conservation of energy that can be translated into power train exercises on production or horticulture machinery. In this experiment. students can visualize gear ratios and speed on a familiar ten speed bicycle. By placing an inch pound torque wrench on each axle, the input and output torque of the ten speed can be measured through all ten gears.
Students can then directly observe the relationship between a speed ratio and torque ratio.
The principle of the conservation of energy is revealed on a familiar speed bicycle. The scientific principle underlying the practical use of electricity is a mystery to many. Students have great difficulty visualizing magnetic lines of force and the induction of current in conductors. One experiment that helps students visualize magnetic lines of force is the placing of a bar magnetic on the screen of your overhead projector. Place a piece of acetate over the magnet and turn the projector on.
