A painter uses a fixed pulley to raise a 1-k can of paint a distance of 10 m,what is the ima??
IMA= 0.1
To determine the ideal mechanical advantage (IMA) of a fixed pulley, you need to know the number of supporting strands of rope or cables that are attached to the pulley system. In the case of a fixed pulley, the IMA is always equal to 1.
A fixed pulley does not provide any mechanical advantage in terms of reducing the amount of force required to lift an object. Instead, it changes the direction of the force applied. When using a fixed pulley, the force required to lift the object is equal to the weight of the object being lifted.
In this scenario, the painter uses a fixed pulley to raise a 1 kg can of paint a distance of 10 m. Since the IMA of a fixed pulley is always 1, the force required to lift the can of paint is equal to its weight.
The weight of an object can be calculated using the formula:
Weight = mass × acceleration due to gravity
In this case, the mass of the can of paint is given as 1 kg. The acceleration due to gravity is approximately 9.8 m/s^2.
Weight = 1 kg × 9.8 m/s^2 = 9.8 newtons (N)
Therefore, the force required to lift the can of paint using the fixed pulley is 9.8 newtons (N).
