Question

Mounted directly to it and coaxial with it is a pulley with a much smaller mass and a radius ofr=0.230m. The flywheel and pulley assembly are on a frictionless axle. A belt is wrapped around the pulley and connected to an electric motor as shown on the right. The turning motor gives the flywheel and pulley a clockwise angular acceleration of 1.67rad/s^2

. The tension T_uin the upper (taut) segment of the belt is 145N.

a. 0.230m
b. 1.67rad/s ^2
c. 145N
d 0.230m and 1.67rad/s ^2

Answer 1

To calculate the tension in the upper segment of the belt, use the equation: Tension = (Mass of Flywheel) * (Radius of Pulley) * (Angular Acceleration). However, the mass of the flywheel is not given in the question.

Step-by-step explanation:

The student is asking about the tension in the upper segment of a belt connected to a flywheel and pulley assembly. The given information includes the radius of the pulley (0.230m) and the clockwise angular acceleration of the flywheel and pulley (1.67rad/s^2). To find the tension in the upper segment of the belt, we can use the equation:

Tension = (Mass of Flywheel) * (Radius of Pulley) * (Angular Acceleration)

Substituting the given values, we get:

Tension = (Mass of Flywheel) * (0.230m) * (1.67rad/s^2)

However, the mass of the flywheel is not given, so we cannot calculate the exact tension without that information.
