Question 7
A boy uses a simple pulley to pull
10 m.
block up a ramp. The height of the ramp is 4 m and the length of the ramp is
Assuming that the ramp is frictionless, what is the ideal mechanical advantage of the ramp and does the pulley
provide any additional advantage?
A
The ideal mechanical advantage of the ramp is 0.4, and the pulley makes it easier to pull the
block up the ramp.
B
The mechanical advantage of the ramp is 2.5, and the pulley does not provide any additional
mechanical advantage.
с
The mechanical advantage of the ramp is 10, and the pulley does not provide any additional
mechanical advantage.
D
The mechanical advantage of the ramp is 40, and the pulley does provide an additional
mechanical advantage.
