A Jaguar XK8 convertible has an eight-cylinder engine. At the beginning of its compression stroke, one of the cylinders contains 499 cm ^ 3 of air at atmospheric pressure (1.01\times 10^5 Pa}) and a temperature of 27.0 degrees C. At the end of the stroke, the air has been comp...

I thought maybe I mixed up the order, and that I should have done (3,0,0) - (-1.3,2.4,0), point minus "effective origin" (the rotation axis) which makes more sense, this changes it to 12.67k, is that correct?

A force F = 0.8 i + 2.5 j N is applied at the point x = 3.0 m, y = 0 m. Find the torque about the point x = -1.3 m, y = 2.4 m. Hmm, (this is essentially just a vector problem) I know you're supposed to find the position vector r and take the cross product of r x F, the fo...
