Question 1.
What is the formula for the Coriolis component?
Show hintHide hint
Think of how relative motion and rotation combine.
Question 2.
What does $\boldsymbol{\omega}$ represent?
Show hintHide hint
Consider it like the speed of rotation.
3Question 3.
What is the formula for the Coriolis acceleration?
- $a_{cor} = \\boldsymbol{\\omega} \\times v_{rel}$
- $a_{cor} = 2 \\boldsymbol{\\omega} v_{rel}$
- $a_{cor} = 0.5 \\boldsymbol{\\omega} v_{rel}$
Show hintHide hint
Look for the equation derived from combining sliding and rotation.
4Question 4.
True or False: The Coriolis component is always directed parallel to the sliding motion.
- True
- False
Show hintHide hint
Recall the definition of the directionality of the Coriolis effect.
Question 5.
A slotted arm mechanism is rotating at an angular speed of 10 rad/s. A point on the link slides with a relative speed of 4 m/s. Calculate the Coriolis component acting on the point.
Show hintHide hint
Remember to use the correct multiplication.
Question 6.
In a robotic arm with a crank system, if the angular velocity changes, describe how this affects the Coriolis component concerning a point sliding along the arm.
Show hintHide hint
Think about how rapid changes in one part of the system affect the rest.
