Statics - slopes, pulleys and weights
Hi Guys, got the following diagram but need to know how I can relate forces in terms of a coordinate system chosen so that I can express the magnitude of each weight in terms of its mas and g.
Note, the system is in equilibrium and m>2Msin(alpha) and the particle A is on the point of slipping up the slope.
Also, how can I use the conditions for equilibrium, together with the propoerties of a model pulley to find the scalar equations relating to the magnitudes of forces?
Finally, does anyone know what the co-efficient of static friction between particle A and the plane looks like?
