Question

Three frictionless cylinders are supported in a cradle as r(A)=90 cm, r(B)=r(C)=60 cm, m(A)=200 kg, m(B)=m(C)=100 kg
a) Draw separate FBDs of each cylinder.
b) Find all the forces acting on cylinder B. Be sure to unambiguously indicate the directions of each force.*
c) For the case when there is no contact force between A and C, find the remaining reactions on cylinder A.

Expert Solution

Step 1

Given that,

$M a s s o f t h e c y l i n d e r A, m_{A} = 200 k g, M a s s o f t h e c y l i n d e r B, m_{B} = 100 k g, m a s s o f t h e c y l i n d e r C, m_{C} = 100 k g, R a d i u s o f t h e c y l i n d e r A, r_{A} = 90 c m, R a d i u s o f t h e c y l i n d e r B, r_{B} = 60 c m, R a d i u s o f t h e c y l i n d e r C, r_{C} = 60 c m,$

(a) Drawing the free body diagram of each cylinder as shown below.
