Find:

1-    The tension in the cable ‘F’ due to friction force and weight.  

Mass  ‘m’= 4 kg, Angle ‘q’ = 30o

Coefficient of friction between the two surfaces = 0.5                         

 

 

 

 

 

 

2-    The force acting on the cable ‘F’.        

Man’s mass = 70 kg, Elevator acceleration = 0.4 m/s2

 

 

 

 

 

 

3-    The reactions at point ‘A’ due to force ‘F’.

Force ‘F’ = 200 N, cantilever length ‘L’ = 300 mm

 

 

 

 

 

 

 

4-    Reaction ‘R’ at point B.  
F = 10 N, a = 20 mm, b = 130 mm.
