The scalar triple product computes the magnitude M of the moment of a force vector F about a specified line. It is M = (r × F)

The scalar triple product computes the magnitude M of the moment of a force vector F about a specified line. It is M = (r × F) . n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line.

Use MATLAB to compute the magnitude M for the case where F = [12, -5, 4] N, r = [$3, 5, 2] m, and n = [6, 5, -7].

Since the function approaches ∞ as x tends to 2 and 5. We can choose our x-limits just around 2 and 5. For instance

x ∈(0, 1.95) ∪ (2.05, 4.95) ∪ (5.05, 7)

The above intervals are not hard and fast and can be varied as per the convenience.

The MATLAB command to plot the functions is shown below:

What must be the magnitude and direction (specified by the angle e in the drawing) of the third force Fs such that the vector sum of the three forces is 0 N?

Three forces are applied to an object, as indicated in the drawing. Force F1 has a magnitude of 32.0 newtons (32.0 N) and is directed 30.0° to the left of the +y axis. Force F2 has a magnitude of 21.5 N and points along the +x axis. What must be the magnitude and direction (specified by the angle e in the drawing) of the third force Fs such that the vector sum of the three forces is 0 N?

A hollow ball has mass M=2.0kg, radius R=0.35m, and moment of inertia about the center of mass I=(2/3)MR2. The ball is thrown without bouncing, to the right with an initial speed 2.0m/s and backspin. The hoop moves across the rough floor (coefficient of sliding friction = 0.25) and returns to its original position with a speed of 0.5 m/s. All surfaces and the hoop may be treated as ideally rigid. Develop an expression for angular velocity of the hoop as...
