Answer:
we have to make another question we maxed it out again lol
Explanation:
Answer:
(a) 19.25 N-m
(b) 25.67 N-m
(c) 0 N-m
Explanation:
Given:
Length of the pedal arm (L) = 0.177 m
Downward force
= 145 N
Magnitude of torque is given by the formula:

Where, 
(a)
Given:
°
Therefore, torque is given as:

Therefore, the torque is 19.25 N-m.
(b)
Given:
°
Therefore, torque is given as:

Therefore, the torque is 25.67 N-m.
(c)
Given:
°
Therefore, torque is given as:

Therefore, the torque is 0 N-m.
