On the end far of the beam, an object of mass m 32 kg is hanging. The beam is making an angle of8-45, at point A with respect to the + x-axis. The cable makes an angle φ -22° with respect to the-x-axis at B. Assume-e+ φ Assume ψ = θ + φ. ©theexpertta.com e, 14% Part (a) Select the correct free body diagram. In the figure the tension is T horizontal and vertical components of the support force are S and Sy. Fa is the weight of the beam, and F is the weight of the mass ka de 14% Part (b) What is the lever arm for the weight of the beam, lB, about the point A? 圏( 14% Part (c) What is the lever arm for the the weight of the mass, lm? 14% Part (d) Write an expression for the magnitude of the torque about point A created by the tension tr in terms of the given variables and trigonometric functions 14% Part (e) what is the magnitude of the tension in the cable in Newtons?
