hello,
I have some trouble understanding the force vector of a loaded pulley shaft:
the pulley is driven by the shaft with a torque T, the pulley on his turn is driving a belt.
because of Newton 3th law there's tension in the belt as shown,
ok, now the question: many books state that the green force is the shaft force => how can this be true:
the shaft load is de resultant force : adding those 2 red force vectores , so the shaft load must be a vector that is oriented toward right instead of that green force.
the green force is de reaction of the pulley support = reaction of the shaft
in shaft calculation they use the green force vector as shaft load...
do not understand it !
grtz
