If an object is in static equilibrium, there must be no net external torque: A) Group of answer choices about an axis located at the edge of the object. B)about an axis located at the object's center of gravity. C)about an axis located beneath the object's center of gravity. D) about any axis.
Describe a situation in which there is a net external torque on an object but it’s angular velocity both magnitude and direction is constant?
A grinding wheel is initially at rest. A constant external torque of 50N*n is applied to the wheel for 20 s, giving the wheel an angular speed of 600 rev/min. The external torque is then removed, and the wheel comes to rest 120 s later. a) Find the amount of inertia of the wheel b)Find the frictional torque, which is assumed to be constant
Q2 A rotational mechanical system is shown in Figure 2.1. T(t) is the external torque and is the input to the system. 01(t) is the angular displacement of inertia Ji and O2(t) is the angular displacement of inertia J2. C and C are friction coefficients and K, and K2 are spring constants. (a) Draw the free-body diagrams for J; and Jz. (7 marks) (b) Derive the equations of motion for the system shown in Figure 2.1. (8 marks) (c) Using...
a dynamic delivers 3.0A at 120V to an external circuit when operating at 120rpm. what torque is required to drive the generator at this speed if the total power losses are 400W?
