Q.3) Block B is supported by a spring and connected by a cable to collar A which
slides on the smooth vertical bar. The mass of collar A is 10 kg and that of
block B is 30 kg . The spring is unstretched when h=0.15m. If the system is
in static equilibrium when h=0.3m, determine the spring constant k.
Q . 3 ) Block B is supported by a spring and
