The drawing shows a jet engine suspended beneath the wing of an airplane. The weight W of the engine is 12000 N and acts as shown in the drawing. In flight the engine produces a thrust T of 54200 N that is parallel to the ground. The rotational axis in the drawing is perpendicular to the plane of the paper. With respect to this axis, find the magnitude of the torque due to each of the following forces:

Question

The drawing shows a jet engine suspended beneath the wing of an airplane. The weight W of the engine is 12000 N and acts as shown in the drawing. In flight the engine produces a thrust T of 54200 N that is parallel to the ground. The rotational axis in the drawing is perpendicular to the plane of the paper. With respect to this axis, find the magnitude of the torque due to each of the following forces: 
a. weight
b. thrust
picture has a plane with an angle of 32 degrees between the wing and the body, and the engine thrust is parallel to the body of the plane and the weight is perpendicular to the body of the plane

Elena · Accepted Answer

(a) Torque1= W•L•sinα = 12000•2.5•sin32°=… (b) Torque2=T•L•cosα=54200•2.5•cos32°=…
