A horizontal force of 10.1 N is applied at an angle of 34.9 degrees to the knob of a 71.1 cm wide door. What torque is produced to open the door? Give your answer in N-m.

The body in the figure is pivoted at O. Three forces act on it in the directions shown: FA = 12.0 N at point A, 7.70 m from O; FB = 15.0 N at point B, 2.60 m from O; and Fc = 25.0 N at point C, 3.50 m from O. Taking the clockwise direction to be negative, what is the net torque about O? Number i -56.26 Units 160° N•m 90°/ B 135%

Please asap

Can somebody help please ?

Hi please help:  A 80-N plank is free to rotate around point P (see figure). Find the magnitude and direction ("+" for CCW or "-" for CW) of the torque due to the weight of the plank, and the forces F1= 120N and F2 = 160N.

A uniform ladder 5.0 m long rests against a frictionless, vertical wall with its lower end 3.0 m from the wall. The ladder weighs 140 N. A man weighing 620 N climbs slowly up the ladder. Start by drawing a free-body diagram of the ladder. What is the actual frictional force when the man has climbed 1.0 m along the ladder? [Hint: Draw a free body diagram to determine what forces are at play. Then use the torque formula (T = Fxrx sine) to find the net torque.]

10.0 N 30.0° 12.0 N ,9.00 N Consider the figure above, which shows a brass axle of radius a attached to an aluminum wheel of radius b. What is the total Torque on the device about an axis passing through the brass axle at O?? Assume that the positive direction is into the page. Here, you should assume the following quantities: a = 5.5 cm and b = 13.2 cm. %3D Express your answer in N-m.

A wrench 0.8 meters long lies along the positive y-axis, and grips a bolt at the origin. A force is applied in the direction of (0,-1,-3) at the end of the wrench. Find the magnitude of the force in newtons needed to supply 100 newton-meters of torque to the bolt. Force: newtons

If you hold your arm outstretched with your palm upward, the force to keep your arm from falling comes from your deltoid muscle. Assume that the arm with hand has mass 4.25 kg and the distances and angles shown. What is the magnitude of the torque must the deltoid muscle provide to keep the arm in this position, in N·m? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

A solid cylindrical disk has a radius of 0.11 m. It is mounted to an axle that is perpendicular to the circular end at its center. When a 71- N force is applied tangentially to the disk, perpendicular to the radius, the disk acquires an angular acceleration of 200 rad/s². What is the mass of the disk? Number Units α
