a.
To explain: the way to increase the horizontal forward force without increasing the total force.
a.

Answer to Problem 26E
Decreasing the angle
Explanation of Solution
Given information:
Angle of
Calculation:
Lowering the angle will increase the
Thus the horizontal forward force can be increased without increasing the total force by decreasing the angle.
b.
To explain: the disadvantages of increasing the horizontal forward force without increasing the total force.
b.

Answer to Problem 26E
It will cause back pain and muscle cramps
Explanation of Solution
Given information:
Angle of
The
Calculation:
Lowering the angle means the person has to change his or her posture. Thus it will cause back pain and muscle cramps.
