You have one steel rod and one copper rod with the same cross sectional area ( 4 cm2 ) and both of them are under a force of 200 N. Supposed that you model them using FEA to find the internal forces. How much do you expect the stress values differ

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

explanation:

-reverse card

it would be c. predictability
