To reduce the drag coefficient and thus improve the fuel efficiency of cars, the design of side rearview mirrors has changed dramatically in recent decades from asimple circular plate to a streamlined shape.

Am i stupid o dont really know

Assuming the torsional yield strength of a compression spring is 0.43Sut and the maximum shear stress is equal to 434MPa. What is the factor of safety if the spring is a music wire (A=2170MPa and m=0.146) with a wire diameter of 4mm?

If you touch a downed power line, covered or bare, what's the likely outcome?

Work done by a system during a process can be considered as a property of the system. a) True b) False

When the compression process is non-quasi-equilibrium, the molecules before the piston face cannot escape fast enough, forming a high-pressure region in front of the piston. It takes more work to move the piston against this high-pressure region.
