- When opening a door you push on it perpendicularly with a force of 75 N at a distance of 0.875 m from hinges. What torque , in newton meters are you exerting relative to the hinges?Can you help me with this physics question? A force vector (2, -1, 4)N acts on a particle at the position (1, -3, 0)m. What is the torque due to this force about the origin?I need help filling out the table of which forces are being applied, the y, and the torque

(a) What is the torque on the particle about the origin, in unit-vector notation? = N: m (b) What is the angle between the directions of r and Torque is the cross product of a position vector (extending from a chosen point, here the origin, to the particle) and a force vector. Did you take the cross product in unit-vector notation? Do you remember how find the angle between two vectors by taking a dot product in both unit-vector notation and also in magnitude-angle notation? (You can similarly use a cross product to do this.) Do you remember how to find the magnitude of a vector from its components?Consider an unsuccessful attempt to take off a tire using a wrench to loosen the bolts. Assume the wrench is 0.3m long and are you able to apply a 200N force Because the tire is flat you can only apply your force at a 60° angle. What is the torque at the center of the bolt. You find a tire jack and are now able to apply 200N of force at an 80° angle. Is the resulting torque more or less and what is the new torque.find the total force experienced by the figure spire and the net torque on the spire pls dont skip steps
- Mutiple choice: The torque is rotational counterpart of force, but it is not force. It has tendency of rotating objects. The torque is more effective when, (1) force is larger (2) force is far from axis of rotation (3) angle between r and the force is zero a) Only (1) is correct b) Only (2) is correct c) All (1), (2), and (3) are correct d) Both (1) and (2) are correctWhen opening a door, you push on it perpendicularly with a force of 55.0N at a distance of 0.850m from the hinges. What torque are you exerting relative to the hinges?Three forces each 8 N are directed clockwise along the sides of an equilibrium triangle 5m on a side. Is the triangle in equilibrium with respect to (a) linear motion? (b) rotary motion? Determine the resultant force and the resultant torque about the center.
