QUESTION:
Problem 185HP
A 100-hp car engine has a drive shaft rotating at 2000 RPM. How much torque is on the shaft for 25% of full power?
ANSWER:
Solution 185HP
Step 1 of 2:
A car engine having power P has a driving shaft rotating at angular speed ⍵. We are going to find the torque if 25% of the full power is used.
The full power P = 100 hp = 100 x 746 W or 100 x 746 J/s
The angular speed of the shaft ⍵ = 2000 RPM or 2000 x 0.1047 rad/s
