1.a Working within an XY coordinate system, How many forces does a roller connection resist?

b Also In the SI unit system, how do you convert a mass to a weight?

Multiply the mass by the acceleration of gravity 9.81 m/s2.

Multiply the mass by the acceleration of gravity 32.2 ft/s2.

The term mass is interchangeable with the word weight from a statics point of view.

You have to determine the center of mass, and that is what weight means.

Expert Solution

1. a) The roller connection resists motion only in one direction.

b) In SI system we convet a mass to weight by multiplying the mass with acceleration of gravity 9.81m/s^2.

The center of mass is the mean position of the mass in an object. Then there's thecenter of gravity, which is the point where gravity appears to act. For many objects, these two points are in exactly the same place. But they're only the same when the gravitational field is uniform across an object.
