Reducing friction helps to minimize energy loss, making the machine more efficient. This allows the machine to transfer more of its input force or energy into useful work, increasing its ideal mechanical advantage.
c) It is less than the idle mechanical advantage. The actual mechanical advantage of a machine is always less than the ideal mechanical advantage due to factors like friction and energy losses in the system.
Wear and tear of moving parts would be reduced. Less energy would be needed to run the machine, as there would be less friction to be overcome. A well lubricated machine is more efficient than a neglected machine with unoiled parts.
Friction reduces the mechanical advantage (IMA) of a simple machine by causing energy losses in the form of heat. As friction increases, the effectiveness of the machine in transmitting force or lift decreases, ultimately lowering the mechanical advantage.
Reducing friction increases the efficiency of movement and decreases the energy required to overcome it. This can lead to less wear and tear on surfaces in contact and prolong the lifespan of mechanical parts.
Greasing a ramp reduces friction between the ramp and the box, making it easier for the box to slide. This reduction in friction increases the mechanical advantage of the system, allowing the box to move with less effort.

No, the ideal is without friction.
Wear and tear of moving parts would be reduced. Less energy would be needed to run the machine, as there would be less friction to be overcome. A well lubricated machine is more efficient than a neglected machine with unoiled parts.
Mechanical Efficiency is the ratio of Actual mechanical advantage to ideal mechanical advantage.Efficiency will be maximum when Actual mechanical advantage equals that of ideal.But practically not possible.Actual mechanical advantage will be less due to friction,heat,deflection etc.avoiding these loses will increase the machine efficiency.

Mechanical advantage is determined by physical measurement of the input and output forces and takes into account energy loss due to deflection, friction, and wear. The ideal mechanical advantage, meanwhile, is the mechanical advantage of a device with the assumption that its components do not flex, there is no friction, and there is no wear.
To increase the mechanical advantage of a wheel and axle system, you can either increase the radius of the wheel or decrease the radius of the axle. This will result in a greater difference in radii, which enhances the mechanical advantage. Additionally, reducing friction in the system can also improve its overall efficiency.
Ideal mechanical advantage is the mechanical advantage when there is no friction. It is the mechanical advantage when the efficiency of the pullefy system is 100%. It is a constant for that system of pulleys. Therfore it is not affected by increasing or decreasing the load. But actual mechanical advantage will be less than this ideal mechanical advantage due to friction. In other words the efficiency will be less than 100 %. If the efficiency is 80%, it implies 20% is wasted due to friction while lifting a load. If we increase the load the friction also increases and hence the efficiency will decrease with the load.
The mechanical advantage of the pulley system is the inertia and friction of the unbalanced and balanced forces acting on the mechanical advantage which is part of the pulley system....
Friction is not typically considered when calculating the ideal mechanical advantage. The ideal mechanical advantage assumes no energy losses due to friction, but in real-world applications, friction can reduce the efficiency of a machine.
