You are to conduct a series of trials. For each trial the inclination of the plane is set to an angle theta, ranging from 0^(@)to 90^(@) and an object is released from rest at the top of the stationary inclined plane. The coefficient of static friction between the object and the inclined plane is mu_(s). In each case below, predict the observed outcome for the trial. In the following equation 'tumble' means 'tip' over and rotate' and 'sliding' means NO tumblingCase3 : The object is a cube and mu_(s) is very large (mu gt gt 1)

Answer»

the cube will remain at REST for SMALL theta and slide down only for theta greater than a certain non-zero value
The cube will stay on the INCLINE as if it were glued to it, for all `theta`
The cube will move relative to the inclined plane only for `theta=90^(@)`
The cube will tumble down only for `theta GT 45^(@)`
