The friction coefficient is c1=0.2 between two bodies A,B. The friction coefficient is c2=0.18 between body B and the ground. If mass mA=0.5kgr and mB=1kgr , what is the minimum force P so that the two bodies start sliding?(we consider that there is no friction at the rope).
If T1 is the friction force for A, the equilibrium for the body A is
And because the body A starts to move
For the body B the equilibrium is
And because the body B starts to move
With the acceleration of gravity g=10m/sec2
We solve (1),(2),(3),(4),(5),(6)
Based on Figure 1, we get: where:...
The rod of the picture is loaded with the force 2...
Calculate the maximum allowable shear force Vmax...
