Movable pulleys allow you to adjust your exercise to target different muscles or work them in different ways, and adjust the machine to better work with your body size and shape.

The answer will depend on the distance that the 400 grams has to be moved.
A fixed pulley is different from a movable pulley because a movable pulley has one end of the rope attached to it fixed on an unmoving object. The pulley is free to move with the rope. You pull the other end of the rope. Also, a movable pulley multiplies the applied force (effort force) and therefore has more mechanical advantage. A fixed pulley is attached to something that doesn't move, while one end of the rope is holding the weight, while the other is for pulling.A fixed pulley confers no mechanical advantage, but will convert motion in one direction into another direction.A movable pulley system, if the pulleys change their distance from each other, will confer a mechanical advantage.
There are information about weight lifting in books, magazines, and websites. Exercises and machines or weights to do weight lifting can be found at many stores. Before beginning any weight lifting be sure to talk to your doctor.
1. The fixedpulley - requires more effort than the load. 2. The movable pulley - moves with the load which allows for less effort than load. 3. The combined pulley - effort is less than half the weight of the load
A fixed pulley is a pulley that is attached to a structure and does not move;changes the direction of the effort force used to life a load by a person or a spring scale and if you use a spring scale then you will need a person to pull the spring scale done to see how far she/he pull it A moveable pulley is a pulley that supports the load and is not fixed in place;reduces the amount of effort force needed to pull to lift the load when she/he pulls the spring scale then it will tell she/he pulls it.
By W.W.L.A (World Weight Lifting association) No body Builder can Lift 650Kg On any Weight Lifting Machines The only Way 650Kg can Be Lifted is by hydraulic Or Heavy Lifting machinery
some are but not all "Sir Legna Added" No, trampolines are more like a spring machine due to there reactions. A pulley is more used for lifting weight.
No. If you are, say, lifting a weight the amount of work done is the same whether you use a pulley or not. However, you may not be able to actually lift the weight unless you use a pulley. But the amount of work done will be the same with or without the pulley.
Because you need to overcome inertia before you can lift anything
Depending on the type of pulley system you have (Fixed/ movable/ combined pulley) using either of these will give you mechanical advantage. The different pulley types are designed to even the weight of the object your pulled out, this will enable you to lift heavier objects with a lighter pull
