4 cards from this section. Quick, good the night before a test.
What is the formula for calculating inertial force?
Think about how mass and acceleration relate to forces.
Define D'Alembert's Principle.
What does it allow us to do in dynamics?
What does D’Alembert's principle help to analyze?
Remember the context of forces in motion.
True or False: Tangential forces enhance an object’s acceleration in circular motion.
Consider how speed changes with these forces.
A pendulum of mass 2 kg swings with an angular acceleration of 1.5 rad/s². Calculate the resulting tangential force acting on the pendulum bob.
Use the length of the pendulum as the radius.
A slider-crank mechanism has a crank radius of 0.75 m and an angular velocity of 4 rad/s. Determine the centripetal force for a mass of 3 kg moving in a circle.
Make sure to square the angular velocity before multiplying.
