A uniform cubical crate is 0.575 m on each side and weighs 900 N. It rests on the floor with one edge against a very small, fixed obstruction. At what height above the floor must a horizontal force of 625.0 N be applied to the crate to just tip it?

Expert Solution

net torque about the obstruction is

where:
torque weight box
torque of the horizontal force

torque weight box

where:
box weight

distance from the obstruction to the line of action of the box

evaluated numerically

torque of the horizontal force

where:
box weight

height of force F

evaluated numerically

negative because the housing rotates clockwise

finally

if

height above the floor must a horizontal force of 625.0 N be applied

An object that weighs 1180 N rests on a lever at a point 0.370 m from a support. On the same side of the support, at a distance of 3.00 m from it, an upward force with magnitude F is applied. Ignore the weight of the board itself. If the system is in equilibrium, what is F? Express your answer in Newtons. where P = 1180 and x = 0.370. N

A uniform ladder is 16 m long and weighs 240 N. In the figure, the ladder leans against a vertical, frictionless wall at height h = 7.0 m above the ground. A horizontal force F→ is applied to the ladder at distance d = 2.8 m from its base (measured along the ladder). If force magnitude F = 46 N, what are (a)x-, (b)y-components of the force of the ground on the ladder? If F = 140 N, what are...

A cubical box is filled with sand and weighs 578 N. We wish to "roll" the box by pushing horizontally on one of the upper edges. (a) What minimum force is required? (b) What minimum coefficient of static friction between box and floor is required? (c) If there is a more efficient way to roll the box, find the smallest possible force that would have to be applied directly to the box to roll it. (Hint: At the onset of...
