these are all common units used to measure height
Answer:
Explanation:
Given
mass of block resting on wedge is ![M_1](https://tex.z-dn.net/?f=M_1)
mass of block hanging vertically is m
coefficient of static friction
Let T be the tension in rope
thus for Equilibrium T=mg
![M_1g\sin \theta -T-f_r=0](https://tex.z-dn.net/?f=M_1g%5Csin%20%5Ctheta%20-T-f_r%3D0)
is friction force
![f_r=M_1g\sin \theta -T](https://tex.z-dn.net/?f=f_r%3DM_1g%5Csin%20%5Ctheta%20-T)
substitute the value of T
![f_r=M_1g\sin \theta -mg](https://tex.z-dn.net/?f=f_r%3DM_1g%5Csin%20%5Ctheta%20-mg)
Also ![f_r=\mu M_1g\cos \theta](https://tex.z-dn.net/?f=f_r%3D%5Cmu%20M_1g%5Ccos%20%5Ctheta%20)
Direction of Friction can either be directing upward or downward depending upon which side system goes after it is released from equilibrium or about to release.
![-f_r](https://tex.z-dn.net/?f=-f_r%3CM_1g%5Csin%20%5Ctheta%20-mg%3Cf_r)
![-\mu M_1g\cos \theta](https://tex.z-dn.net/?f=-%5Cmu%20M_1g%5Ccos%20%5Ctheta%20%3CM_1g%5Csin%20%5Ctheta%20-mg%3C%5Cmu%20M_1g%5Ccos%20%5Ctheta%20)
