Recall the experiment activities. If the meterstick is pivoted at the 20cm mark, a force of 4.6N is applied at 85cm mark, what is the maximum possible torque (in unit of Nm) by the force?
Recall the experiment activities. In the experiment, you have a meterstick of mass 64.9 grams. You found its center of mass is at 49.6cm. If the meterstick is pivoted at the 10cm mark, What is the torque magnitude (in unit of Nm) by the weight of the meterstick?
Two torques are applied on a pivoted rod. One is a clockwise torque of magnitude 27.4 Nm, the other is a counterclockwise torque of magnitude 19.9Nm. What is the total torque on the rod (in unit of Nm)? (Don't forget to include proper sign to indicate whether the total torque is clockwise or counterclockwise)
A force of 15 N is applied parallel to a lever arm of length 10 m. What is the resulting torque? 0 Nm 5 Nm 75 Nm 150 Nm
Recall your experimental setup from Lab 05A: a constant force was applied to a disc by attaching a mass to a light string wrapped around a mass-less pulley and hanging the mass over the edge of the apparatus. In the lab, you used energy conservation arguments to derive an expression for the angular velocity of the disc after the mass had fallen a distance x. Your goal now is to use kinematics and dynamics to confirm your expression. Use the...
