Answer:
The weight lifter would not get past this sticking point.
Explanation:
Generally torque applied on the weight is mathematically represented as
T = F z
To obtain Elbow torque we substitute 4000 N for F (the force ) and 2cm for z the perpendicular distance
So Elbow Torque is
To obtain the torque required we substitute 300 N for F and 30cm
So the Required Torque is
Now since it mean that the weight lifter would not get past this sticking point
