Question

NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Two transmission belts pass over sheaves welded to an axle supported by bearings at B and D. The sheave at A has a radius of 2.5 in., and the sheave at C has a radius of 2 in. Know that the system rotates at a constant rate. Assume that the bearing at D does not exert any axial thrust and neglect the weights of the sheaves and axle. Consider the value of P = 36 lb. Determine the tension T. Assume that the bearing at D does not exert any axial thrust and neglect the weights of the sheaves and axle. (You must provide an answer before moving on to the next part.) The tension T is lb.

00:01 To solve this problem first i just write the given data.

00:03 Ra is given as 2 .5 inch and rc is given as 2 inch.

00:08 Taking moment about x axis so i just write this value.

00:13 So on further simplification i can write 24 multiplication ra minus 18 ra plus 30 rc minus t rc is equal to 0.

00:29 Just putting the data here.

00:32 So the expression will become 24 multiplication 2 .5 minus 18 multiplication 2 .5 plus 30 multiplication 2 minus t multiplication 2 is equal to 0.

00:51 So the value of t will be equal to 37 .5 ib.

00:58 Now solving part b of this problem.

01:04 So here i can write the value of ta as 24 plus 18 which is equal to 42 ib.

01:13 Tc is equal to 30 plus t which is equal to 30 plus 37 .5 that will be equal to 67 .5 ib.

01:27 Now going to draw the diagram.

01:31 So just look at it carefully.

01:32 The diagram looks like this which i am drawing here.

01:36 This is the rough diagram which i am drawing here.

01:40 So just look at it carefully.

01:45 This is the rough diagram here.

02:00 So this is x -axis.

02:03 This point is point d.

02:07 This is dz.

02:09 This is dy.

02:11 Here it is tc is equal to 67 .5 ib.

02:17 Here this value is 6 inch.

02:20 This is also of 6 inch...
