Problem 1: Consider the figure below. A block of weight "W" slides on a horizontal surface with a coefficient of Coulomb friction "P". It is attached on its left face to a vertical surface by an ideal spring having constant "K" and an ideal dashpot having constant "p". A horizontal force "F" is rapidly applied to the right face of the block. Motion of the block is quantified by the coordinate "x" having origin at the initial position of the right face of the block. - Disregard all dynamic effects. -The force F is initially zero, is increased sufficiently for the block to move, is held constant for a brief period of time, and then is returned to zero. For the conditions given, answer each of the following. Note: As appropriate distinguish between Perfectly Plastic and Strain-hardening Plastic. LAF a. If f0, p=0, K=0 what material behavior discussed in class is best represented by the movement of the block? Explain your answer. No credit without explanation. b. If f0, =0, K=0 what material behavior discussed in class is best represented by the movement of the block? Explain your answer. No credit without explanation. c. If f=0, =0, K=0 what material behavior discussed in class is best represented by the movement of the block? Explain your answer. No credit without explanation. d. If f = 0, 0, K=0 what material behavior discussed in class is best represented by the movement of the block? Explain your answer. No credit without explanation. Problem 1: Consider the figure below.
