Chapter 2, Practice Problem 2/067 For an interval of motion the drum of radius b =…

Chapter 2, Practice Problem 2/067 For an interval of motion the drum of radius b = 137 mm turns clockwise at a constant rate w = 2.7 rad/s and causes the carriage P to move to the right as the unwound length of the connecting cable is shortened. The distance h = 1.1 m. Use polar coordinates r and and find the magnitudes of the velocity v and acceleration a of P in the horizontal guide when the angle = 20°. Check your solution by a direct differentiation with time of the relation x2 + 2 = r. Answers: m/s m/s2
