To understand rigid-body rotation about a translating axis. An exhausted bicyclist pedals somewhat erratically. The angular velocity of the front tire, as measured with respect to an axis fixed at the tire’s center, is given by ω(t)=12t−14sin(2t) for t≥0 where t represents the time in seconds and ω(t) is measured in radians per second. Assume that the tires roll without slipping The bicycle’s front tire has a spot of paint on it. Take the spot’s position at time t=0.00s to be at angle θ=0.00 radians with respect to an axis parallel to the ground (and perpendicular to the axis fixed at the tire’s center) and take angles in the direction of the tire's rotation to be positive. What angular displacement θ(2) has the spot undergone between 0.00 and 2.0 s? If the tire’s radius is 23 cm, what is d, the magnitude of the spot’s displacement after 2.0 seconds? Which one of the following statements describes the spot’s motion at t=2.0s? The wheel’s angular acceleration is constant and the…
The power of an engine running at 125 rpm is turned off and the engine comes to rest at the end of 2 min and 40 sec. Assuming that there is no slipping between the belt and pulley surface and that the deceleration is uniform, find 1) the average speed in radians per second of the engine pulley in coming to rest; 2) the total angular distance traveled in revolutions, radians and degrees in coming to rest; 3) the distance in feet traveled by a belt running on the pulley in coming to rest, if the pulley diameter is 3ft.
A system of machines shown has a motor which has a radius of 1 inch that begins rotating at w=41 (1-e^-t) rad/s, where t is in seconds. The smooth pulley 4 inches in radius and the blades (16 inches radius) has the same center of rotation and mass. Assuming no frictional force is developed throughout the system, calculate the normal acceleration of point P in inches/seconds^2 at time t=0.5sec.
