Answer: Suppose that you can lift no more than 650 N
Chapter 11, Problem 16E(choose chapter or problem)
Suppose that you can lift no more than \(650 \mathrm{~N}\) (around 150 lb) unaided.
(a) How much can you lift using a \(\text { 1.4-m-long }\) wheelbarrow that weighs
\(80.0 \mathrm{~N}\) and whose center of gravity is \(0.50 \mathrm{~m}\) from the center of the wheel (Fig. E11.16)? The center of gravity of the load carried in the wheelbarrow is also
\(0.50 \mathrm{~m}\)from the center of the wheel.
(b) Where does the force come from to enable you to lift more than \(650 \mathrm{~N}\) using the wheelbarrow?

ANSWER:
Solution 16E
Here we shall have to first calculate the mechanical advantage. Mechanical advantage is the ratio of the length of effort arm to that of the load arm.
Here, the length of the effort arm is
Length of the load arm is
