Question

part A- if youre stationary without slipping, determine the magnitude of the normal force exerted on you by the wall.

ML Ice wall You are pushing against a wall while your body is slanted, as shown. Stylish! The wall is made of smooth ice and so has essentially zero friction. The floor, however, is made of rough sandstone and so has coefficients of friction Ms and uk, both of which are non-zero. Model yourself as a uniform one-dimensional rod of mass M and length L. Your body makes an angle relative to the ground, as shown. Known: M, L, 0, Ms.Mog (Remember: There is no friction between the wall and you.)

Answer 1

Dear student,

Find this solution, and RATE IT ,If you find it is helpful .your rating is very important to me.If any incorrectness ,kindly let me know I will rectify them soon.

Thanks for asking ..

For Nwall equilibrium Ex=0 wall = 2 0 Nwall = Mg Ni also, along vertical, o f=MNI from 0 &0, (wall = els mg) Ant Normal by wall.
