3 cards from this section. Quick, good the night before a test.
What is static friction?
Think about motion status.
Describe viscous friction.
Connect this to speed.
What type of friction opposes the start of motion?
Think of a stationary object trying to move.
True or False: Viscous friction decreases as speed increases.
Consider how liquids behave.
A robotic hand attempts to lift an object weighing 5kg from a resting position. Calculate the initial torque if static friction is 3 Nm, and viscous friction coefficient is 1 Nm/(m/s) with a speed of 0.2 m/s.
Consider static friction as constant at rest.
In a system where both static and viscous frictions must be balanced, what happens if the robot's speed exceeds the limits of these frictions? Describe and compute an example scenario.
Examine how values correlate under different conditions.
