The rigid bar is pinned at a and supported by two aluminum rods, each having a diameter of 1 in. a modulus of elasticity eal = 10(103) ksi, and yield stress of (sy)al = 40 ksi. if the bar is initially vertical, determine the angle of tilt of the bar when the 20-kip load is applied.

the answer would be c

yup its correct its: c) b b

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d
