Q1. Two bars AB and BC are linked at B as shown in Fig. Q1. The end A of bar AB is free to rotate but otherwise cannot move, while the end C of bar BC is free to rotate and moves vertically as shown in Fig. Q1. Rod AB makes an angle angle with the vertical. with the horizontal and rod BC an C x WBC αBC B WAB; αAB Fig. Q1 The point C moves upwards vertically with a constant speed of Vc, which gives rise to angular velocities of bars AB and BC of WAB and WBC and angular accelerations of α AB and αBC respectively. For the given lengths of AB and BC together with angles 0, & and Vc, determine: (a) WAB and WBC (b) α AB and α BC- Give angular rates in deg/s and angular accelerations in deg/s². You should use the values of lengths of AB, BC, 0, & and Vc shown against your Student

The drawing shows a rectangular piece of wood. The forces applied to corners B and D have the same magnitude of 20 N and are directed parallel to the long and short sides of the rectangle. The long side of the rectangle is twice as long as the short side. An axis of rotation is shown perpendicular to the plane of the rectangle at its center. A third force (not shown in the drawing) is applied to corner A, directed along the short side of the rectangle (either toward B or away from B), such that the piece of wood is at equilibrium. Find the magnitude and direction of the force applied to corner A.
