Yes it can because it had lots of force
A. The efficiency of the ramp is 54.6 %.
<h3>Velocity ratio of the ramp</h3>
V.R = distance moved by effort/distance moved by load = L/h
V.R = (6.12)/(1.53) = 4
<h3>Mechanical advantage of the ramp</h3>
M.A = Load/Effort
M.A = (451 x 9.8)/(2025)
M.A = 2.183
<h3>Efficiency of the ramp</h3>
E = (M.A / V.R) x 100%
E = (2.183 / 4) x 100%
E = 54.6 %
Thus, the efficiency of the ramp is 54.6 %.

Answer:
2.5kN.m
Explanation:
Torque is directly proportional to pitch diameter
= Ta/Tb= Da/Db
=120/Tb= 0.25/0.5
Tb= 2.469kN.m approx 2.5kN.m
Answer:
80 times 12=960
Explanation:
You have to do the equation for work, the equation is work= force times distance, the force here is 80newtons, the distance is 12meters, so you would do 80 times 12 to get your answer of 960
It's known as the law of equal areas
