The mechanical advantage of a machine is calculated by dividing the output force by the input force. In this case, the input force is 49 N and the output force is the force required to lift the 50-kg mass, which can be calculated using the equation F = m * g, where F is the force, m is the mass, and g is the acceleration due to gravity (approximately 9.8 m/s^2).
F = (50 kg) * (9.8 m/s^2) = 490 N
The mechanical advantage is therefore:
Mechanical Advantage = Output Force / Input Force
= 490 N / 49 N
= 10
Therefore, the mechanical advantage of this machine is 10.
F = (50 kg) * (9.8 m/s^2) = 490 N
The mechanical advantage is therefore:
Mechanical Advantage = Output Force / Input Force
= 490 N / 49 N
= 10
Therefore, the mechanical advantage of this machine is 10.
