What is the definition of a tipping force?
The maximum force required to tip an object over
The minimum force required to tip an object over
The force of the surface working back on an object
The force needed to make an object start moving
Which of the following free body diagrams shows an object about to tip over?
Which force(s) only occur where the object is touching the surface, at point P? (Select all that apply)
Applied (FA)
Weight (W or Fg))
Friction (Ff)
Normal (FN)
If an object is symmetrical, such as the box shown, where is its center of gravity

Surface Area
Volume
Weight
Density
If the tipping force of an object is 50 lb, will a 65 lb applied force tip it over?
Yes, because FA > T
Yes, because FA < T
No, because FA > T
No, because FA < T
If the tipping force for an object is 75 lb, will a 100 lb applied force tip it over?
Yes, because FA > T
Yes, because FA < T
No, because FA > T
No, because FA < T
If the tipping force of an object is 15 lb, will a 12 lb applied force tip it over?
Yes, because FA > T
Yes, because FA < T
No, because FA > T
No, because FA < T
If the tipping force of an object is 100 lb, will a 50 lb applied force tip it over?
Yes, because FA > T
Yes, because FA < T
No, because FA > T
No, because FA < T
In order for an object to be in static equilibrium, what must be true (Select all that apply)
All forces must be 0
The sum of all forces in the y direction must be zero
The sum of all forces in the x direction must be zero
The sum of all moments about point P must be zero

10 lb
40 lb
80 lb
5 lb
If a 10 lb force is applied to the top of this box, will it tip over?
Yes, because FA > T
Yes, because FA < T
No, because FA > T
No because FA < T
If a 1 lb force is applied to the top of this box, will it tip over?
Yes, because FA > T
Yes, because FA < T
No, because FA > T
No because FA < T
In the tipping force formula T=W*d/h, d is equal to
The width of the object
Half the width of the object
The horizontal distance from the tipping point to where the Weight occurs
The vertical distance from the tipping point to where the applied force occurs
In the tipping force formula T=W*d/h, h is equal to
The height of the object
Half the height of the object
The horizontal distance from the tipping point to where the Weight occurs
The vertical distance from the tipping point to where the applied force occurs
True or False: If an object is symmetrical, like the box shown below, its center of gravity is at the center of the object
True
False
True or False: If an object is not symmetrical, like the shell shown below, its center of gravity is at the center of the object
True
False
