Question

The engine of an automobile develops 176 hp when rotating at a speed of 1340 rpm. What torque (in foot-pounds) does it deliver?

I tried using some kinematic equations, but that didn't work at all. Then I tried doing something where I would take an integral, but then I don't know how far it went. I searched the website, and everywhere else online, so this is my last resort. Thanks in advance.

Answer 1

Torque * angular velocity = power

176 hp = 131,243 Watts or N m/s

1340 rpm = 140 radians/s

so Torque = (131,243 / 140) Newton meters

Answer 2

937 N m = 691 foot pounds
