PE Problem for Module 2.1: Solve the complex truss below by the method of substitution. See component reactions at the supports. Match the axial bar force by ticking the circle that corresponds to your answer according to your solution. * 2m 16KN 4m 16 KN a 1m 4m 4m 10 KN 10 KN

bar AB is Q1) A homogeneous of M supported at either end by a cable as shown in figure beside. If the stress is not to exceed 75 MPa in bronze and 110 MPa in steel. And the diameter of bronze cable is 25 mm while for steel cable is 20 mm. Calculate the maximum safe mass M that can be carried by these cables. (1300) Bronze A 8m Steel

In the figure below, a weight W is suspended from point D of a beam AD. The beam is held up by rod BC. Neglect the mass of the beam AD and rod BC. Which of the following is true (select all that apply). Beam AD is a three force member The direction of the force in rod BC (i.e whether the force is tension or compression) is known Beam AD is a two-force member Rod BC is a two-force member 4m 4m The line of action of the force in rod BC is known The magnitude of the force in rod BC is known 3m B D W
