Weight of mass (N)


Height of inclined plane (m) 

Length of inclined plane (m) 

Force on inclined plane (N) 

Force on pulley (N) 

Force on pulleyplane system (N) 

 What is the theoretical mechanical advantage of the pulley? This
is calculated by the number of ropes used to lift the cart.
 What is the theoretical mechanical advantage of the plane? Divide
the length of the plane by the height of the plane.
 What is the theoretical mechanical advantage of the compound machine
(the planepulley system)? This is the product of the individual mechanical
advantages.
 What force was required to lift the cart originally (in step one)?
 What is the experimental mechanical advantage of the plane? Divide
the weight of the cart by the force on inclined plane. Compare this
to your theoretical advantage calculated above.
 What is the experimental mechanical advantage of the pulley? Divide
the weight of the cart by the force on the pulley. Compare this number
to your theoretical advantage calculated above.
 What is the experimental mechanical advantage of the compound machine?
Divide the weight of the cart by the force on the planepulley system.
Compare this number to your theoretical advantage calculated above.
