suppose the biceps were surgically reattached three centimeters farther toward the person\'s hand. If the same bowling ball were again held in the person\'s hand, how would the force required for the biceps be affected? Explain? (Select all that apply.)

It would require more force because the force acts closer to the heavy bowling ball.

It would require less force because of the larger distance between the elbow and the location where the force from the biceps acts.

It would require more force because of the larger distance between the elbow and the location where the force from the biceps acts.

It would require less force because the torque for each newton of force from the biceps is greater.

It would require more force because the force is less nearly perpendicular to the moment arm.

Solution

In bowling, a certain amount of torque is required by the hand. Now as we know that the torque about a point is equal to the multiplication of force and the distance from that point. Now in this case as the distance increases because of surgical reattachment so the force required for bowling will be less for the same amount of torque.

So both 2nd and 4th statements are true and are applicable.
