What is the magnitude of the torque in Nm? Whole numbers only here. i j k mean the unit vectors in the x y and z direction respectively. Normally written with a cute little hat or ^ on top of them. Remember that torque = r X F. position vector = r = 3.29 i + 4.06 j + 5.47 k where r is in metres and applied force = F = 581 i + 721 j - 838 k...
(10 points) The work done by a force is the scalar product of the force and displacement vectors, i.e W F x and the power is given by the dot product between the force and the velocity vector, i.e. P F.V . For a force vector, F 2x i+10y j- (x+5y) k and a displacement vector, x=t i+t j+2t k, calculate the work done by the force and the power required. Based on your answer, what can you say about...
To understand two different techniques for computing the torque on an object due to an applied force.Imagine an object with a pivot point p at the origin of the coordinate system shown (Figure 1). The force vector F⃗ lies in the xy plane, and this force of magnitude F acts on the object at a point in the xy plane. The vector r⃗ is the position vector relative to the pivot point p to the point where F⃗ is applied.The torque on the...

I have no idea how to get the answer to Practice Problem 11.
Apparently its suppose to be: (150 m, 213.6 degrees)
Also I can get the Newtons for Practice problem 14, but I can't
quite figure out how to get the degrees for theta. Apparent answers
are: (1684 N, 169 degrees), (1684 N, 348 degrees).
