(b) A uniform beam AB of length 6.0 m is placed on a horizontal surface and then tilted at an angle of 31° to the horizontal, as shown in Fig. 2.1.2.[2]90NА6.0 mWYX 317BFig. 2.1 (not to scale)The beam is held in equilibrium by four forces that all act in the same plane. A force of 90Nacts perpendicular to the beam at end A. The weight W of the beam acts at its centre ofgravity. A vertical force Yand a horizontal force X both act at end B of the beam.(i) State the name of force X.on(1)(ii) By taking moments about end B, calculate the weight W of theN [2]Crackets.erg 0221-10(iii) Determine the magnitude of force X.N[1]magnitude of force X = |
