6 / 16

What type of torque on a body is caused by its weight; and occurs when the center of gravity of the body is not located on the axis of rotation?

7 / 16

What kind of graph shows the relationship between stress and strain, characteristic of a material?

8 / 16

What is the pressure of one atmosphere, and serves as a reference level for pressure?

9 / 16

What is the point where the weight vector is attached?

10 / 16

What causes mass to become so dense, that it collapses in on itself, creating a singularity at the center surround by an event horizon?

11 / 16

What is the name for the high tide created when the Moon, the Sun, and Earth are along one line?

12 / 16

What is the time required for a satellite to complete one orbit?

What is the circular motion of the pole of the axis of a spinning object around another axis due to a torque?

15 / 16

What is the behavior in which material deforms irreversibly, and does not go back to its original shape and size when load is removed and stress vanishes?

16 / 16
