Question

<p>The wheels, axle, and handles of a wheelbarrow weigh W = 68.6 N. The load chamber and its contents weigh WL = 638 N. The drawing shows these two forces in two different wheelbarrow designs. To support the wheelbarrow in equilibrium, the man's hands apply a force to the handles that is directed vertically upward. Consider a rotational axis at the point where the tire contacts the ground, directed perpendicular to the plane of the paper. Find the magnitude of the man's force for both designs.<img class="mceBlock" src="https://s3.amazonaws.com/answer-board-image/719817f5-503e-4ba1-b1c7-337622df8158.gif" border="0" alt="uploaded image" /><br /><br />(a) F = <br />(b) F =</p>

Explanation / Answer

SM=0=(-638)(.4)-(68.6)(.6) +(F)(1.3) F=22.97 N upward Diagram 2: SM=0=(-68.6)(.6)+(F)(1.3) F=31.66 N upward
