Question
Which object(s) are in translational equilibrium?
Which object(s) are in rotational equilibrium?
Which object(s) could be rotating clockwise at a constant angular speed?
Which object(s) could be moving upward at a constant speed?
Which object(s) could be at rest (neither rotating or translating)?
Which object(s) could be rotating clockwise with a decreasing angular speed?
Please explain the process behind each step as well as answer the question.
1. Use the diagrams below to answer the questions: 2F 2F F 2F 3 a. Which object(s) are in translational equilibrium? b. Which object(s) are in rotational equilibrium? c. Which object(s) could be rotating clockwise at a constant angular speed? d. Which object(s) could be moving upward at a constant speed? e. Which object(s) could be at rest (neither rotating or translating)? f. Which object(s) could be rotating clockwise with a decreasing angular speed?Explanation / Answer
Here,
a) for translational equilibrium
net force = 0
the net force is zero for
C , D
the objects C and D are in translational equilibrium
b)
for rotational equilibrium
Net torque acting pn the object = 0
the objects are :
A , B , D
c)
for rotating at a constant angular speed ,
Net torque acting pn the object = 0
the objects are :
A , B , D
d)
for moving at constant speed
net force = 0
the net force is zero for
C , D
the objects C and D are in translational equilibrium
e)
for objects at rest
net force = 0 , net torque = 0
the object is D
