When you change the mass of a load, it creates less friction because there is less for gravity to act on.

What force opposes the effort force?
load force and friction oppose the effort force
Whats the force needed to move a load?
the force on the load is the force exerted by the simple machine on the load. All simple machines involve a force on the load and an effort force.
What is the force that tends to keep a load from moving?
Friction, I think.
In a machine what force does the effort force try to overcome?
It depends, there are two forces, the load's inertia and friction.
What is the difference between a dead load and a live load?
A dead load is a permanent force, acting on a structure.This includes the weight of the structure itself.A live load is a changing, or non-permanent force acting on a structure.This includes the force of the wind and the weight of things that are in or on a structure.

How would the amount of force that is needed to put the load up the inclined plane be reduced?
Reduce the friction
What are the units that friction is measured in?
The coefficient of friction is dimensionless; it has no units.
How does the position of a fulcrum affect the load?
does the positoin ef the fulcrum affect the force necessary to lift a weihgt
How do you calculate the friction in a pulley?
To find the velocity ratio of a pulley, you must first find the effort and load distances. then you divide the two and there you have you VR (velocity ratio).
Why the coolie carrying load in the head is not doing any work scientificall?
it is because the displacement of load being horizontal,is normal to the direction of force of gravity ie.,cos 90' which is zero but he surely does some work if we consider it against the force of friction.
How can the efficiency of an inclined plane be increased?
Efficiency is the ratio of power output to power input. It is not the ratio of forces or distances. You can move a load using less force by reducing the gradient of the plane. But what you gain in reduced force you lose in having to travel a greater distance to raise the load through the same height. There is, therefore, no net advantage. The only way to increase the efficiency is to reduce the friction. This can be done by lubricating the plane, or load (or both), or by placing rollers between the load and the plane - so that there is rolling friction rather than sliding friction.
Effect of changing load on alternator?
by changing load its terminal voltage changes.
