일반물리학 1 — Equilibrium and Elasticity: Problem 4

4 In Fig. 12-17, suppose the length L of the uniform bar is 2.75 m and its weight is 185 N. Also, let the block's weight W = 300 N and the angle \theta = 30.0°. The wire can withstand a maximum tension of 500 N. (a) What is the maximum possible distance x before the wire breaks? With the block placed at this maximum x, what are the (b) horizontal and (c) vertical components of the force on the bar from the hinge at A?
