Determine the force in each member of the truss, and state if the members are in tension or compression. Set 0 = 30°. 3 kN 15m B 2 m 2 m 4 kN

The shear leg derrick is used to haul the 200-kg net of fish to the dock. Determine the compressive force along eanch of the legs AB and CB and the tension in the winch cable DB. Assume the force in each leg acts along its axis. a=4.6 m b=3.8 m c=2.1 m D x a A b B b

1- Determine the force developed in the member BC and reactions at the pin support A. Take G1 = 5Kg.

For the curved beam, determine the horizontal and vertical components of force at pin A and vertical reaction at the rocker B. Neglect the weight of the beam. 500 N 200 N 10% 15% 2m B
