Two blocks are connected by a massless string and are held in position by another massless string along a frictionless incline (as shown in the figure). Let M1 = 52.0 kg, M2 = 30.0 kg, and q = 11°. Calculate the tension in the string connecting the two blocks.
so..first i am going to use f=ma
the forces that need to be taken into acount is the weight and noraml force..so i have Fn+w=ma, but the boxes are stationary so the a=0
then i have Fn+w=0...so w=mg so now i have Fn+mg=0
i find Fn=-15288 N which is on the y-axis of my free-body diagram and then i try to solve for the x component on the digram using 11 deg and Fn...tan 11deg=15288/x
but that is not the right approch...please help me
