belt friction (flat belt and v-belt) lab reportFull description
Friction stir welding is the process which have been famous from last 2 decades. The experiments carried are presented in bulk and no significant method is present to make the researcher understand what exactly the experiment was. For understanding t

Details about the different kinds of guideways and also the kinds of Mechanical Transmission system
The observations from the experiments are as expected from the theory. But after the graphs were drawn, it was found that the points are s omewhat are scattered.
Does the pulley radius affect the belt tension or coefficient of friction?
Radius of the pulley does not affect the belt tension or coefficient of friction. Belt tension is only affected by friction and the weight. Coefficient of friction depends on the material and the surface condition of the two surfaces.
What is the effect of a worn groove on the performance?
In the worn groove surface area touching the belt and groove is less, and also energy loss due to action of wedging in and pulling out is lower in worn belt since it is not tightly fit in to pulley. The coefficient of friction is higher in correct when compared with the worn worn belt.
In a belt drive is there a l imit upon pulley size?
Slippage may occur with ratios over 15:1. The belt will sli p on a very small pulley because it cannot wrap tightly around a small radius

Flat belt
The coefficient of friction is much higher for the worn belt. The coefficient of friction is the lowest was for the round belt. This means it is not very efficient in transmitting power since it would slip easily.
Why do you think that the Vee belt is the most popular belt form for power transmissions?
Vee belts (also known as V-belt or wedge rope) solved the slippage and alignment problem. It is now the basic belt for power transmission. They provide the best combination of traction, speed of movement, load of the bearings, and long service life.
