question

The smooth circular cylinders of figure each of weight w = 100 N and radius r = 6 cm are connected by string AB of length l = 16cm and upon a horizontal plane, supporting a third cylinder of weight Q3= 200 N and radius r = 6cm above them. Find the tension S in the string AB and the pressure produced by the floor at points of contact D and E ?

Question
solution

Given :-

Two smooth cylinders weight (Q1,Q2) = 100 N

Radius of the all cylinders = 6 cm

String AB length = 16 cm

upper cylinder weight (Q3) = 200 N

Tension S in the string = ?

Pressure produced by the floor at points of contact

D and E = ?

SOLUTION
slide5

In this we use lami’stherom :-

Now we find the value of Ra and Rb

For finding the value we make a free body diagram of cylinder Q3

By that we get the value of the angle between Rb and known weight

slide6

And the angle between Ra and known weight

And the angle between Ra and Rb

slide7

After that we get the value of

Ra and Rb = 1.55 N

This Ra and Rb are the tension S = 1.55 N

Since both the smooth sylinder are in the point contect of the surface so the value of the pressure at the point contect will be

Ra + Rb = weights of all cylinder

Since Ra and Rb are equal so

slide8

2 Ra = 400 n

Ra = 200 paskal

Here Ra be the pressure
