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 ● with the horizontal and rod BC an angle with the vertical. Vc WBC; αBC | B WAB α AB File preview A 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 αAB and αBC respectively. For the given lengths of AB and BC together with angles Є, & 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, ☀ and Vc shown against your Student
