4) A steel beam and a cable both of negligible mass are used to support a 1600 kg block. The beam is 3.50 m long and 3.00 cm in diameter. The cable is 1.0 cm in diameter. (a) Calculate the tension in the cable. (b) Determine the horizontal and vertical components of the force of the wall on the beam. (C) How much compression force is acting on the beam? (d) How much will the length of the beam be compressed? (e) How much is the cable stretched due to tension? elastic modulus for steel 200 x 10 ° N/m² 450

The traffic light shown in (Figure 1) has a mass of21 kg . Take h= 3.5 mm.

Warren truss and a series of moving loads are shown in Figure 2. Assuming the loads can travel in either direction along the center of the truss. i) Draw the influence line for the force in member FC. ii) Calculate the maximum force (tension or compression) that can develop in member FC due to series of moving loads which acts along the bottom chords of the truss.

Find the force in each member of the truss shown below. Be sure to state whether the member is in tension or compression. 8 ft B 375 lb A C 16 ft-+ 8.2 ft 500 lb OD
