Question

Why does Changing moment arm change the torque​

Answer 1

Explanation:

The moment arm (lever arm) of a force system is the perpendicular distance from an axis to the line of action of a force. In other words, moment arm determines the quality of the torque. An important concept to remember is that the moment arm changes with the angle of application of the force (angle of insertion).

Answer 2

Answer:

Here is your Answer..

Explanation:

A common example of the effect of moment arm and angle of application have on torque is the patella's affect on quadriceps torque. As you can see below, the patella bone increases the angle of application of the quadriceps tendon and therefore moment arm, thus increasing the amount of torque the quadriceps can create.
