A pin jointed frame (Figure 2) support a gravity load of 5k at C. An impulse cause the frame to vibrate freely in vertical direction with a velocity of 0. 2 ft/s. Calculate: 1. Static force corresponding to peak dynamic displacement. 2. Time required to complete 10 cycles during free vibration Diameter of both members is 9/8 in Take E= 29,000 ksi
