b)What is the Theory about the Incline Friction experiment? (as detailed as possible for this part)(At least 500 words)

Answer 1

(a) The errors / uncertainties that occur in the inclined experiment: which could occur in this experiment can be sometimes with the block or the inclined plane used. Make certain that both the block and the plane are dry. If they're wet the friction experienced with both the objects may be extraordinary , as a result ensuing with a one of a kind coefficient of friction than that of the authentic.

Another error that may arise is with the strain skilled with the aid of the thread with the pulley. Make positive that the thread is immediately and parallel with the inclined plane so that genuine fee of force may be calculated. Make certain to regulate the thread to a parallel position after every trial.

(b) Theory behind experiment: The concept at the back of this experiment is to locate the coefficient of friction that is skilled between the plane and the curler as discussed beneath. They could be definitely calculated by means of the method for mu as given above.

To start the experiment, Put the block on the inclined plane and slowly increase the angle of inclination until the block just begins to move downwards. Now at this point measure the height (h) of the inclined plane and the base (b)

Add more weight, say 5 gm and boom the perspective of inclination and find the point wherein the block just starts to move down on the aircraft. Now at this immediate, degree the peak (h) of the willing aircraft and the the bottom again,

Repeat this procedure for each case by including similarly weights and for this reason mark h and b in a table. Find their imply values and this would provide you with the fee of Coefficient of friction (mu).

To locate the downward pressure experienced by means of the block on the willing plane the price of the burden of the block and the angle of inclination may be used, Hence, downward force acting at the frame is ( F = mgsine)

in which weight w=mg

hope you understand it well Thank you.
