Q1. Two bars AB and BC are linked at B as shown in Fig. Q1. The end A of bar AB is free torotate but otherwise cannot move, while the end C of bar BC is free to rotate and movesvertically as shown in Fig. Q1. Rod AB makes an angle → with the horizontal and rod BC anangle with the vertical.VeCФWBC; αBCxBWAB αABFig. Q1The point C moves upwards vertically with a constant speed of VC, which gives rise to angularvelocities of bars AB and BC of WAB and WBC and angular accelerations of αAB and αBCrespectively. For the given lengths of AB and BC together with angles O, & and Vc, determine:(a) WAB and WBC(b) αAB and αBC-Give angular rates in deg/s and angular accelerations in deg/s².You should use the values of lengths of AB, BC, O, 6 and Vc shown against your StudentNumber in the Case Table on Pages 4 and 5.

*24. D The drawing shows a bicycle wheel resting against a small step whose height is h = 0.120 m. The weight and radius of the wheel are w = 25.0 N and r = 0.340 m, respectively. A horizontal force F is ap- plied to the axle of the wheel. As the magnitude of F increases, there comes a time when the wheel just begins to rise up and loses contact with the ground. What is the magnitude of the force when this happens? Problem 24
