What would happen to a pulley system if the load were increased?
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.
How does the torque vary when the fan is the load?
When a fan operates as a load, the torque varies based on the speed and the characteristics of the fan itself. As the speed increases, the load torque typically increases due to the increased aerodynamic resistance and power requirements to move air. Conversely, when the speed decreases, the torque required also decreases. This relationship is crucial for understanding fan performance and efficiency in various applications.
Why are distribution transformers frequently designed to develop maximum efficiency at loads that are somewhat lower than rated value?
It is always desirable to run any equipment or device at maximum efficiency for that matter, not only the power transformer. Power transformer maximum efficiency occurs when copper loss is equal to iron loss. (or no load loss equals to load loss). This does not necessariliy mean that maximum efficiency occurs at maximum or full load. Generally the maximum efficiency occurs at relatively less than full load of the transformer.
What is mechanical efficiency in science?
mechanical efficiency is the percent of the energy that you put into a machine that was transferred to the load.
What is the range of thermal efficiency of good IC engine at rated load?
60 to 70%

When is the efficiency maximum in a transformer?
the efficiency is maximum in a transformer when no load loss is equal to load loss.
Which factor increases as the efficiency of a machine increases?
The output work done by the machine increases as the efficiency of the machine increases. This is because efficiency is the ratio of useful work output to the total work input, so as efficiency increases, more of the input work is converted into useful output work.
If load increases then what happens?
If load increases then it will stop completely. Having an overload can cause issues.
What is the relationship between the load on a muscle and its strength of contraction?
Strength of contraction increases as the load increases until the load becomes excessive.

Why the time constant for various inertial loads increases as the size of the load increases?
The time constant for inertial loads increases as the size of the load increases because a larger load has more mass to accelerate, requiring more time for the load to reach steady-state. This is because the inertia of the load is directly proportional to its mass, so a larger load will take longer to respond to changes in input.
Why the load voltage increases when the load used is capacitive?
capacitive reaction
What increases as efficiency of a machine increases?
As the efficiency of a machine increases, the output of the machine for a given input also increases. This means that the machine can do more work with the same amount of energy input. Additionally, the operating costs of the machine may decrease as efficiency improves, since less energy is wasted.
