is used to hold block The spring clamp of Fig. E into the corner. The force in the spring is F = k(€ – lo), where € is the present length of the spring, lo = 15 mm is the unstretched length of the spring, and k = 5000 N/m is the spring constant. Determine all forces acting on mem- ber ABC of the spring clamp and the force exerted by the spring clamp on the block E. B E 30° 30° 40 mm -20 mm20 mm

Q2. Determine the stretch in each spring for equilibrium of the block of mass M. The springs are shown in the equilibrium position Given: M = 2 kg a - 3 m b = 3 m C - 4 m kAB - 30 kAC = 20 kAD - 40 g- 9.81 www D
