The arm of a crane has two steel plates connected with a rivet that transfers the force in pure shear. the rivet is made of annealed aisi 1040 steel and has a circular cross section with a diameter of 25 mm. the load on the rivet is 15 kn. calculate the safety factor according to the von mises criterion.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.
