Acollar with a pulley slides on a frictionless vertical bar gh. a string abcd is wrapped around the pulley, where portion ab of the string is horizontal. a spring with 2 lb/in. stiffness is placed between the collar and point h. the spring has 8 in. unstretched length and 6 in. final length. the collar and pulley have a combined weight of 6.5 lb, and the weights of all other components are negligible. determine the value ofprequired for
equilibrium, and the reaction between the collar and bargh.
