Solution

The correct option is C 2
Length of the sloping wooden plank , $l = 2 m$
Vertical height , $h = 1 m$
We, know that for a inclined plane,
Mechanical Advantage $= \frac{L e n g t h o f t h e i n c l i n e}{v e r t i c a l h e i g h t}$
$\Rightarrow \frac{l}{h} = \frac{2}{1} = 2$

A truck driver can load oil drums into the back of the truck by pushing them up a sloping plank or by lifting them directly. Each drum has a mass of 80 kg, the plank is 3m long and the back of the truck is 0.8m above the ground. How much force would be needed to lift a drum into the truck directly, without using the plank?

A truck driver can load oil drums into the back of the truck by pushing them up a sloping plank or by lifting them directly. Each drum has a mass of 80 kg, the plank is 3m long and the back of the truck is 0.8m above the ground.
