I already know how to find the maximum force (just multiplyingthe maximum acceleration by the mass), but I've got no clue as tohow to find the minimum acceleration when no minimum accelerationhas been found.

In both cases the free body diagram is as shown

Chossing the upward direction as positive,the Maximun tension is obtained by assuming the upward accelerationas positive.

Therefore,

Or

The minimum acceleration is obtained by assuming theacceleration is down.

Therefore, here

The arm weighs 44.0 N. The force of gravity acting on the arm acts through point A. Determine the magnitudes of the tension force t in the deltoid muscle and the force s of the shoulder on the humerus (upper-arm bone) to hold the arm in the position shown.

t=N

s=N
