Explain how to find the torque produced by a force using cross products.
A rectangular bar is hinged at point O. The bar is 3.00 m long and 2.00 m wide. Find the torque resulting from the following force about an axis through point O: F1 = 1 N. Use a positive for a counterclockwise torque and a negative for a clockwise torque.
Explain the concept of torque in your own words.
13 Which is INCORRECT among the following statements? The counterpart of torque in translational motion is force. The counterpart of work in translational motion is mass. Dynamics for rotational motion is analogous to translational dynamics None of the above
Is it possible to apply a net force without a net torque? Explain.
4) Express the radius and force vectors in unit vector notation (assuming the positive x direction is to the right, and the positive y direction is up). Then calculate the torque vector using the cross product. Express the answer a) in unit-vector notation, and b) as a magnitude and direction (the direction of the torque vector). 2.5 m 14 N
1. Calculate the torque about the z-axis pointing out of the page at the origin in the following - figure given that F₁ =3 N, F₂ = 9 N, F3=8 N, F₁=2 N. Hint: Use the sign convention for torques, counter-clockwise rotation corresponds to a torque in the positive z-direction and clockwise rotation corresponds to a torque in the negative z-direction. Which forces produce clockwise rotations and which forces produce counter-clockwise rotations? While using the formula for cross-product A x B= ABsine, remember that is the angle between the tails of the vectors A and B. To determine 0 rearrange the vectors so that their tails coincide.
