Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

Question

Q-4: The refrigerator has a mass of 105 kg and rests on a tile floor. The man pushes horizontally
on the refrigerator trying to move it.
(a) If the coefficient of static friction between the refrigerator and floor is us = 0.27, determine
the minimum force the man needs to push to move the refrigerator, and also does the
refrigerator slip or tip?
(b) The man has a mass of 70 kg, thus determining the smallest coefficient of static friction
between the floor and his shoes so that he does not slip.
(c) If the coefficient of static friction between the refrigerator is us = 0.38, determine the
minimum force the man needs to push to move the refrigerator, and also does the
refrigerator slip or tip?
