Question

A chain pulls tangentially on a 47.5 kg uniform cylindrical gear with a tension of 75.1 N. The chain is attached along the outside radius of the gear at 0.864 m from the axis of rotation. Starting from rest, the gear takes 2.62 s to reach its rotational speed of 1.38 rev/s. What is the total frictional torque opposing the rotation of the gear?

Answer 1

we know 1-33 x2 nds 1-38 x2rt 2-62 TNt to Adso, 1-38*2TC x 47-5 x Lo.8644 75.Ix 0.364 + Tyricien 2.62 6.21193 N m richon magnitude Thus, the tona that op pones the etation has - 6.21198 Nm
