Question

as a trailer is towed in the forward direction, the firce F = 500N is applied to the ball of the trailer hitch. Determine the moment of this force about point O...static problem​

Answer 1

The right approach is "128.578 N-m".

Step-by-step explanation:

Given:

Force,

F = 500 N

then,

`F_y=500 \ Cos30`

`F_x=500 \ Sin 30`

Now,

The moment of force will be:

⇒
`\Sigma M_0=500 \ Cos30* (275)+500 \ Sin30* (38)`

`=500* (√(3) )/(2)* 275+500* (1)/(2)* 38`

`=128578.493`

or,

`=128.578 \ N-m`
