Consider a metal single crystal oriented such that the normal to the slip plane and slip direction are at angles of 60° and 35°, respectively, with the tensile axis. if the critical resolved shear stress is 8 mpa, will the applied stress of 12 mpa cause the single crystal to yield? if not, what stress will be necessary?

A2000 kg car is rounding a curve of radius 200 m on a level road. the maximum frictional force the road can exert on the tires of the car is 4000 n. what is the highest speed at which the car can round the curve?

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
