6. 1.when to use pulley 2.how to use pulley
Answer:
1. Pulleys are generally used to lift objects, especially heavy objects. The object lifted by a pulley is called the load. The force applied to the pulley is called the effort.
2. If you have a single wheel and a rope, a pulley helps you reverse the direction of your lifting force. So, as in the picture below, you pull the rope down to lift the weight up. If you want to lift something that weighs 100kg, you have to pull down with a force equivalent to 100kg, which is 1000N (newtons).

8. A system of pulleys is more efficient if it has more of this.
Answer:
Work out the efficiency of the pulley system. It is important to remember that NO pulley system is 100% efficient. This is due to friction of the ropes against the pulley wheels and the friction of the bearings of the pulley wheels as they rotate. 100% efficiency is only theoretical..

12. state two advantage og using this pulley system.(refer to the illustration above)
Answer:
The main advantage in the use of pulleys is that the effort becomes less as compared to the normal lifting of the weights. In other words, it reduces the amount of actual force required to lift heavy objects. ... These two advantages in the use pulleys make them an important tool for heavy lifting.
Explanation:
13. state two advantages of using this pulley system.
Answer:
Using a system of pulleys can be much more complex and provide a powerful mechanical advantage — greatly reducing the amount of force required to move an object. If one movable pulley is used (Figure 6), the amount of force required to raise the object attached to the movable pulley is cut in half.

advantages of pulley system
1. Using a system of pulleys can be much more complex and provide a powerful mechanical advantage — greatly reducing the amount of force required to move an object. If one movable pulley is used (Figure 6), the amount of force required to raise the object attached to the movable pulley is cut in half.
2. In the case of a pulley supported by a frame or shell that does not transfer power to a shaft, but is used to guide the cable or exert a force, the supporting shell is called a block, and the pulley may be called a sheave.

16. a system where several pulleys can be used with the same rope is called?
Answer:
A system where several pulleys can be used with the same rope is called a block and tackle system. This system consists of multiple pulleys, or blocks, that are mounted on a fixed or movable frame, and a single rope that is threaded through the pulleys. The rope is looped back and forth through the pulleys to create a mechanical advantage, allowing the user to lift or move heavy objects with less force. The block and tackle system has been used for centuries in various industries, such as construction, shipping, and transportation, as well as in recreational activities such as rock climbing and sailing.
17. If the efficiency of the pulley system is 75%what is its mechanical advantage.
Answer:
I
M
A
=

Explanation:
The mechanical advantage (MA) of a machine is a measure of how much the force is multiplied. It is the ratio of load/effort:
M
A
=
L
E
Because energy is conserved, this is done as a trade - off against the distance the effort moves compared with the load.
The ideal mechanical advantage (IMA) is the ratio of the distance moved by the effort/distance moved by the load.
I
M
A
=

If we divide MA by IMA we get:

In an ideal world this ratio would equal 1. However there are energy losses due to friction etc. We usually express this ratio in terms of efficiency
