A system consisting of two fixed and two movable pulleys has a mechanical advantage of 4.00. If a force of 124 N is exerted, which weight can be raised?
Four times as much, 496 N, can be lifted. The mechanical advantage tells you that.
answer
To determine the weight that can be raised using the system of pulleys, we need to use the formula for mechanical advantage:
Mechanical Advantage (MA) = (Weight to be raised) / (Force applied)
Given that the mechanical advantage is 4.00 and the force applied is 124 N, we can rearrange the formula to solve for the weight:
Weight to be raised = Mechanical Advantage × Force applied
Plugging in the values:
Weight to be raised = 4.00 × 124 N
Weight to be raised = 496 N
Therefore, a weight of 496 N can be raised using the given system of pulleys.
To determine the weight that can be raised using a system of pulleys with a given mechanical advantage, we need to understand the concept of mechanical advantage.
Mechanical advantage is the ratio of the output force to the input force in a machine or system. In the case of pulleys, it is equal to the ratio of the weight being lifted to the force applied.
In this system, the mechanical advantage is given as 4.00. This means that for every 1 unit of force applied, the system can lift 4 units of weight.
Now, to find the weight that can be raised with a force of 124 N, we need to multiply the force applied by the mechanical advantage:
Weight = Force applied × Mechanical advantage
Weight = 124 N × 4.00
Weight = 496 N
Therefore, a weight of 496 N can be raised using a force of 124 N in this system of pulleys.
