Question

A 2.0-m-high box with a 1.0-m-square base is moved across
a rough floor as in Fig. 9–89. The uniform box weighs 250N
and has a coefficient of static friction with the floor of 0.60.
What minimum force must be
1.0 m
exerted on the box to make it
slide? What is the maximum
height h above the floor that this
force can be applied without tip-
ping the box over? Note that as
the box tips, the normal force
CG
2.0 m
FN
and the friction force will act at
the lowest corner.
