I need help with part D. Thank you.
Problem 12: A uniform beam of length L and mass M has its lower end pivoted at the floor, making an angle θ with the floor. A horizontal cable is attached at its upper to a point A on a wall. A box of mass M is suspended from a rope that is attached to the beam one-fourth L from its upper end.
25% Part (a): Write an expression for the y-component Py of the force exerted by the pivot on the beam. 2 Mg - Correct!
25% Part (b): Write an expression for the tension T in the horizontal cable AB. 5/4Mg cotanθ - Correct!
25% Part (c): Write an expression for the x-component Px of the force exerted by the pivot on the beam, in terms of T. T - Correct!
25% Part (d): What is the tension in the horizontal cable, in newtons, if the mass of the beam is 44 kg, the length of the beam is 5 m, the angle is 21°? Grade Summary: T=824 Deductions Potential 10
