i bunk class and watch your lectures.....thanks sir

[@achyuth_rj]

When calculating M, why didnt you consider the moment due to Rb and the pulley force at D?

[@pranilpawar6763]

Sir, really liked how u simplified the every problem in your each video. Thanx alot from me and my friends.. 👍

[@kurunandanshishaudhiya1159]

answer my question

[@kurunandanshishaudhiya1159]

You can check. ....shaft is not safe at this dia......it will fail due to principle stress. ....

[@mangeshdeshmukh7633]

Nice Tutorial Sanmit , can you elaborate more on T eq ( twisting moment concept ) how it is derived, had it been calculated @ point c only coz u r using value of B'moment @ point c only then what about @ point D ...Please help on that.

[@yuktipatil8044]

A transmission shaft is supported on two bearings which are 1m apart. Power is supplied to the shaft by means of a flexible coupling, which is located to the left of left hand bearing. Power is transmitted from the shaft by means of a belt pulley, 250 mm diameter, which is located at a distance of 300 mm from the left hand bearing. The mass of the pulley is 20 kg and the ratio of belt tension on tight and slack sides is 2:1. The belt tensions act vertically downward. The shaft is made of steel with yield stress 300N/mm2 and the factor of safety is 3. Determine the shaft diameter, if it transmits 10 kW power at 360 rpm from the coupling to the pulley.

its wrong plzzzz correct it..

[@sarojsimkhada8476]

I came here to say same thing better calculate bending moments using equilibrium diagram and making sum of moments=0

[@burakkrbas792]

When we draw the bending moment and shear force diagram, the maximum value of bending moment can be easily find which is 1500 Nm

In this problem why did the lectirer not consider the effect of tension of the belt drives...if the shaft is rotating ot means it is driven by the belt drives therefore the effect of tension in tightside and slack side must be considered

The kilowatt that can be transmitted safely by a shaft varies directly as the number of revolutions it makes per minute and the cube of its diameter. If a shaft 3 centimeters in diameter making 200 revolutions per minute can safely transmit 60-kilowatt, what kilowatt can be safely transmitted by a 2-centimeter shaft making 300 revolutions per minute
