If a student tried to lift a 350 N box upwards with a lever that is 75 cm long, how much force would they need to provide given a fulcrum 20 cm away from the box. 1312.5 N. 93.3 N. 65.6N. 2333N.

Answer:
93.3 N
Explanation:
Applying the equation of moment
M = r * F
r = distance from the applied force to the object = 75 cm
F = force applied = X
Moment of force = load * distance from load = 350 * 20
back to equation
350 * 20 = X * 75
7000 = 75 X
X ( force applied/needed) = 7000 / 75 = 93.3 N
We will take moment about the fulcrum point
Taking, box 350 N at a distance of 20 cm
we can write the moment equation as below:
350 N x 20 cm - X x 75 cm = 0
X = 350 N x 20 cm /75 cm
= 93.33 N
