The formula for torque created by a perpendicular force
What is F *L?
A way in which you can confirm an objects center of mass.
What is balancing is on your finger?
Hooke's law's description.
What is the force required to stretch an object is proportional to the displacement or F=kx
The type of force experienced by the bottom of a beam when a load is placed on top of it.
What is tension?
This bridge is commonly used for highway overpasses due to its simple, inexpensive design.
What is a beam bridge?
The torque produced by a 5 N perpendicular force located .5 m away from a pivot point.
What is 2.5 N*m?
An objects ability to not topple over.
What is stability?
The physical meaning of the slope of a spring force vs stretch graph.
What is, 'k,' spring constant?
The type of force experienced by the bottom of a beam when an upwards force is applied to it.
What is compression?
This bridge is very aesthetically pleasing, but is challenging to build. It is said to be nearly indestructible if built properly, but requires hard ground to support it on each side.
What is an arch bridge?
The torque produced by F1 in the image
What is 0?
Which object is least stable in terms of its center of mass?
a. A tall, narrow tower
b. A low, wide table
c. A person standing upright
d. A cube with equal sides
What is a. a tall, narrow tower?
This physical constant describes the stiffness or stretchiness of a spring.
What is spring constant.
The most stable beam shape from this list: square, circle, rectangle, or triangle?
What is triangle?
This bridge is used to cover long spans of deep water and is known to be very useful in places with high winds and earthquakes.
What is a suspension bridge?
A state in which an object is balanced. Net torque=0.
What is rotational equilibrium?
True or False--the center of mass must always be located within the object.
What is False?
An object's ability to return to its original shape after experiencing a deforming force.
What is elasticity?
This type of beam is supported at one end, as used in balconies.
What is cantilever?
This bridge, while not aesthetically pleasing, is very sturdy and cheap to make. It is commonly used for trains.
What is a truss bridge?
The location on a mobile design where you could hang a 5th mass while maintaining balance.
What is the center of mass of the top dowel?
This determines whether an object will topple over or not.
What is the center of mass is suspended over the ground?
The location of the elastic limit on the graph below:
What is B?
The beam that will bend the least:
-2 m long, supported on one end
-1 m long, supported on one end
-2 m long, supported on two ends
-1 m long, supported on two ends
What is 1 m long and supported on two ends?
This is the type of hybrid bridge design used in the Brooklyn Bridge.
What is a cable stayed, suspension hybrid bridge?
