Mechanical advantage = Effort distance/Resistance distance

Effort distance = D - Fulcrum = 0.5 m
Resistance distance = A - Fulcrum = 2.0 m

Then,
Mechanical advantage = 0.5/2 = 0.25 

Hockey stick is an example of third class where mechanical advantage is less than one as the speed of the end of point A is critical.

Mary pushes a crate by applying force of 18 newtons. Unable to push it alone, she gets help from her friend, Anne. Together they
maw [93]
 <span>This problem is relatively simple, in order to solve this problem the only formula you need to know is the formula for friction, which is: 

Ff = UsN 

where Us is the coefficient of static friction and N is the normal force. 

In order to get the crate moving you must first apply enough force to overcome the static friction: 

Fapplied = Ff 

Since Fapplied = 43 Newtons: 

Fapplied = Ff = 43 = UsN 

and it was given that Us = 0.11, so all you have to do is isolate N by dividing both sides by 0.11 

43/0.11 = N = 390.9 which is approximately 391 or C. 3.9x10^2</span>
