Simple Machines
Simple Machines - In all the above examples, a machine either multiplies or reduces the effect of the force that is applied. A bicycle is a machine which is used to gain speed. We gain speed by exerting additional force. When we try to ride a bicycle up a ste..
Levers
Levers - A simple crowbar can be used to lift a heavy rock with a small effort. The crowbar is an example of a lever. The use of levers was known to the ancient Greeks, and it is reported that Archimedes once remarked "Give me a lever long enough an..
Fixed Pulleys
We can think of a single fixed pulley as a lever of class I where the fulcrum is at the centre and the load and effort arm have the same length. (shown in the figure below) Fixed Pulleys If you pass a string over the pulley with one end carrying a weight and ..

A bicycle is a machine which is used to gain speed. We gain speed by exerting additional force. When we try to ride a bicycle up a steep hill, we soon realize that we gain speed by applying greater force. It is impossible to multiply both the force and gain the speed at the same tim..
Machine
It is a device which helps us to do the work at one point and deliver at another point with a view of accomplishing the work more easily or with a gain in speed. We use machines to multiply force or to change the direction of the force or to increase or decrease the speed etc. Cutting pl..

In this type of lever the effort and the resistance (load) are situated on either side of the fulcrum. Let us consider the lever AB which is used to overcome a load L at B by applying the effort E at A. The fulcrum of the lever is at F as shown in the figure belo..

Best tutor ever. I can actually understand what to do in fraction and decimal division situations
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Thank you very much for helping to me is very important to have my lessons. Because you manage to take good notes in school thank you Tutor Vista
Tutor Vista tutors actually helped me to think through some of the problems instead of just doing them for me.Now i am more confident with math ,Thank you all
