Source sentences:
text: High tensile strength and impact resistance were critical; since the parts are used in the assembly of a cassette intended to contain blood, they must be resilient enough to resist cracking if accidentally dropped.
text: The increased impact resistance of acrylic is another critical factor that helps prevent breakage in transport as well as high traffic areas.
