Mechanical Equillibria

Question 1

translational equillibrium

Answer 1

object is experiencing zero net force - all forces acting on it cancel out. acceleration = 0, velocity constant.

Question 2

rotational motion is caused by…?

Answer 2

caused by the application of torque - force that causes an object to rotate around a fixed point

Question 3

what is torque proportional to?

Answer 3

angle - force applied at 90 degrees give most torque
radius - how far away from the fulcrum force is applied (further away = more torque
force - greater force = greater torque

Question 4

rotational equillibrium

Answer 4

sum of torque in every direction is equal to zero

Question 5

equation for torque

Answer 5

T=rFsin(o)
