Answer:
square cross section. The bar is made of a 7075-T6 aluminum alloy which has a yield strength of 500 MPa, a tensile strength of 575 MPa, and a fracture toughness of 27.5 MPaâm.
Required:
a. What is the nominal maximum tensile stress on the bar?
b. If there were an initial 1.2 mm deep surface crack on the right surface of the bar, what would the critical stress needed to cause instantaneous fast fracture of the bar be?
Answer:
A battery changes chemical energy to <u>electrical</u> energy
A drum changes mechanical energy to <u>sound</u> energy
Explanation:
A battery is a device that stores chemical energy and converts it to electrical energy.
Beating a drum represents a mechanical to sound energy conversion.
In poor weather, you should <u>double</u> your following distance.
