Question 1.
What is the definition of displacement?
Show hintHide hint
Think about the object’s position change.
Question 2.
How do you define velocity in kinematics?
Show hintHide hint
Remember, it includes direction.
3Question 3.
What formula calculates linear velocity for a rotating link?
- v = ω × r
- v = a × t
- v = m × t
Show hintHide hint
Think about how rotation affects distance.
4Question 4.
True or False: Acceleration can be both tangential and centripetal.
- True
- False
Show hintHide hint
Recall the different contexts of acceleration.
Question 5.
Given a rotating arm of length 2m rotating at 5 rad/s, calculate the tangential and centripetal accelerations at a point 1m from the center.
Show hintHide hint
Use the formulas for each type of acceleration.
Question 6.
Consider a four-bar mechanism where the lengths of links and their angles are known. How would you set up the loop closure equations for position?
Show hintHide hint
Remember, the loop should describe the closed path of motion.
