How much effort force is required to life an 11000-N beam using a pulley system with a mechanical advantage of 20?
Efford = 11000 / 20 = 550 N.
To determine the effort force required to lift the beam using a pulley system, we need to understand the concept of mechanical advantage.
Mechanical advantage is a measure of how much a machine amplifies the input force. It is calculated by dividing the output force by the input force. In this case, the mechanical advantage is given as 20.
Mechanical Advantage = Output Force / Input Force
Given that the mechanical advantage is 20, we can use this information to find the effort force needed to lift the beam.
Effort Force = Output Force / Mechanical Advantage
In this case, the output force is equal to the weight of the beam, which is 11,000 Newtons (N). Thus, the equation becomes:
Effort Force = 11,000 N / 20
Now, let's do the calculations:
Effort Force = 550 N
Therefore, a force of 550 Newtons is required to lift the 11,000-N beam using a pulley system with a mechanical advantage of 20.
