A boulder sits at rest on top of a mountain. What conclusion can be made about the forces acting on the boulder? The forces acting on the boulder are balanced (net force equals zero).
I think the statement is true. Manual handling of materials accounts for the primary source of injury in the workplace. This can be found in OSHA. <span>Manual materials handling is the </span>principal source of compensable injuries in the American work force<span>, and four out of five of </span>these injuries<span> will affect the lower back.</span>
I believe it would be compound.
