A solid disk of radius, R = 0.063 m, and mass, M= 0.500 kg, has a small hole drilled through it halfway between its center and outer edge and the disk is pinned to the wall through the hole so that it may rotate freely on the pin.
a) Using a free-body diagram, with the weight of the disk acting at its centre of mass, determine the torque on the system about the axis and determine, using similar arguments as were used for a pendulum for the class notes, the constant k for the linear restoring torque in this case.

- a) By considering a rigid body rotating about the axis O with an angular velocity (w) and acceleration (a) measured postive counterclockwise as shown in the FigQ2(in the attatched image). show that the resultant inertia force components are given by the expression, FX=mw2XG FY=-maXG where XG is the distance of the center of gravity G from the axis of rotation.arrow_forward5) In ice figure skating, a couple execute a “top” (see picture). The centre of mass of the woman (58 kg) is situated 1.3 m from the axis of rotation which is vertical and passes through the centre of mass of the man (85 kg). They are spinning at a constant angular velocity equal to ?? rad/s and the man and woman have moments of inertia, about their own centres of mass, equal to 1.6 and 2.5 kg.m2 respectively. Then the woman grabs the neck of the man. At this point, her moment of inertia decreases to 1.4 kg.m2 and her body centre of gravity is 0.9 m from the axis of rotation. Determine the new angular velocity. Hints: This is a conservation of angular momentum problem, and needs the parallel axis theorem to determine moments of inertia about the axis of rotation. The skaters are moving as one body with one angular velocity, but they each have their own moments of inertia given relative to their own CoMs. For the man, that’s fine…the axis they’re rotating about passes through his CoM,…arrow_forwardIn which of the following cases is the magnitude of the total torque about the center of mass largest?arrow_forward
- An object has its center of mass 7.25 cm from the pivot point of a servo. Assuming that the servo has a maximum torque of 1.75 kg - cm (based on a stall torque of 2.5 kg - cm, reduced by 30% to provide a buffer), what is the maximum mass that the object can be to not exceed the 1.75 kg - cm limit? Round your response to the second decimal place (i.e., #.##).arrow_forwardMutiple choice: The torque is rotational counterpart of force, but it is not force. It has tendency of rotating objects. The torque is more effective when, (1) force is larger (2) force is far from axis of rotation (3) angle between r and the force is zero a) Only (1) is correct b) Only (2) is correct c) All (1), (2), and (3) are correct d) Both (1) and (2) are correctarrow_forward(5) For a body to be stationary in a frame of reference, what conditions must be met regarding forces and torques?

The center of mass of the motorcycle, including the rider, is 88.0 cm above the ground and halfway between the wheels. Assume the mass of each wheel is small compared with the body of the motorcycle. The engine drives the rear wheel only. What horizontal acceleration of the motorcycle will make the front wheel rise off the ground? (There are a number of views on how to do this online, if you have difficulty with this problem look them up. One view is to calculate the torque about the point of contact on the ground and also the around the center of mass and set them equal to each other.)

B) How long will it take?arrow_forwardA solid disk of radius, R = 0.063 m, and mass, M= 0.500 kg, has a small hole drilled through it halfway between its center and outer edge and the disk is pinned to the wall through the hole so that it may rotate freely on the pin. a) Using a free-body diagram, with the weight of the disk acting at its centre of mass, determine the torque on the system about the axis and determine, using similar arguments as were used for a pendulum for the class notes, the constant k for the linear restoring torque in this case. b)The effective mass of the system will be the moment of inertia about the axis which you have already calculated above. Your work above should establish that the system executes SHM with the angle theta as the variable rather than the displacement, x, as was the case for the spring motion we studied in class.
