Cross product.

The Attempt at a Solution


If I'm correct with what I am about to say then, I get this problem but, I want to make sure that I truly get it and am not thinking some incorrect thing and believing it to be true. Basically, can someone please tell me if the point P on the diagram should be point A and whether the 0 or M_O point should be point P?

If what I said is confusing, tell me and I will rephrase it.
Thanks in advance!

Thanks for the confirmation. :)
 

What is the formula for finding the moment M_O about P of a 1000N force?

The formula for finding the moment M_O about P of a 1000N force is M_O = F*d, where F is the magnitude of the force and d is the perpendicular distance from the point P to the line of action of the force.

How do I determine the direction of the moment M_O about P?

The direction of the moment M_O about P can be determined using the right-hand rule. Point your thumb in the direction of the force and curl your fingers towards the point P. The direction your fingers are pointing is the direction of the moment.

What is the unit of measurement for the moment M_O about P?

The unit of measurement for the moment M_O about P is Newton-meter (Nm).

Can the moment M_O about P be negative?

Yes, the moment M_O about P can be negative. This indicates that the direction of the moment is opposite to the direction of the force.

How does the distance d affect the magnitude of the moment M_O about P?

The magnitude of the moment M_O about P is directly proportional to the distance d. This means that if the distance increases, the moment also increases, and vice versa.
