A bucket crane consists of a uniform boom of mass M - 201 kg and length L- 59.09 ft that pivots at a point on the bed of a fixed truck. The truck supports an elevated bucket with a worker inside at the other end of the boom, as shown in the figure. The bucket and the worker together can bc modclcd as a point mass of wcight 195 Ib locatcd at the end point of the boom. Supposc that...
Problem 4 A uniform slender rod of length L- 3 m and mass 2 kg rotates freely (no friction) about hinge at A. Att- 0, the initial angle is B 30 and the initial angular velocity SQUARED is 4.9 rads/s in the counter-clockwise direction. a) What are the hinge reaction forces, acceleration of the center of mass, angular velocity (squared) and angular acceleration as functions of B, b) what are the hinge reaction forces, acceleration of the center of mass...
A pendulum consists of a uniform rod of total mass m and length L that can pivot freely around one of its ends. The moment of inertia of such a rod around the pivot point is 1/3mL^2 The torque around the pivot point of the pendulum due to gravity is 1/2mgLsinθ, where θ is the angle the rod makes with the vertical and g is the acceleration due to gravity. a) Write down the equation of motion for the angle...
