number 6, find 2 tension
Homework Equations
F=μR
The Attempt at a Solution
Okay, so R(reaction force)=Tcos30 Tsin30=F+20
the first tension is found, 68.5.
However, I am not understanding how there can be two tensions, as a result of frictions of 2 directions?? the marking scheme says the other friction is to prevent downward motion, but the tension isn't even downwards? How can there be 2 Tensions at the same time
