Document Summary

Quiz no. 1: the spring is placed between the wall and the 25-kg block. If the block us subjected to a force of f = 550 n. determine its velocity when s = 0. 5. When s = 0, the block is at rest and the spring is uncompressed. Answer: the 35 lbforce has an initial speed of vo = 4 m/s when it is midway between springs a and b. After striking spring b, it rebounds and slides across the horizontal plane toward spring a, etc. If the coefficient of kinetic friction between the plane and the block is k = 0. 6, determine the total distance travelled by the block before it comes to rest. Answer: the block has a mass of 15 slugs and rests on a surface for which the coefficients of static and kinetic friction are k = 0. 4 and s = 0. 5, respectively.

Figure 1 shows a system of two blocks A weighs 1800 N and B weighs 2200 N, are lying on inclined planes. The two blocks are connected by a uniform horizontal rod of weight 800 N. Determine (a) the reaction of each block on the plane surfaces (b) the compression force of the rod on blocks A and B (c) the value of force P to impend the block A upward. Take the coefficient of friction for all the surfaces as 0.3
