## zbay 2 years ago The combination of an applied force and a friction force produces a constant total torque of 36N*m on a wheel rotating about a fixed axis. the applied force acts for 6sec. during this time, the angular speed of the wheel increases form 0-10 rad/sec. the applied force is then removed and the wheel comes to rest in 60sec. Find (a) the moment of inertia of the wheel, (b) the magnitude of the torque due to friction, and (c) the total number of revolutions of the wheel during the entire interval of 66 sec

1. zbay

a) is 21.6 Kg*m^2

2. zbay

b) 3.6 N*m but i can't figure out c

3. ksaimouli

i am have a problem with torque can u help me

4. zbay

I cant try but i can't figure out c on this one so if it's anything like that i may be no good

5. zbay

opps can try to help not can't

6. ksaimouli

no it's easy

the mass of an automobile is 1160 kg, and the distance between its front and rear axles is 2.54m. The center of gravity of the car is between the front and rear tires, and the horizontal distance between the center of gravity and the front axle is 1.02 m. Determine the normal force that the ground applies to (A) each of the two front wheels an to (B) each of the two rear wheels.
