Question

Mechanics

Answer 1

F_2 = 186.3 / 98.8 / 47.7 / 72.2
beta = 303.6 / 123.6 / 236.4 / 56.4

Answer 2

what does 120 N R= 180 N
mean ?

Answer 3

Resultant = 180

Answer 4

The direction of the resultant is the same as the force 120

Answer 5

@phi

Answer 6

What two vectors are we adding to produce the resultant ?

Answer 7

It's the result of adding all the forces

Answer 8

so we are adding 4 vectors?
in terms of mag, angle
<170, 50>
<F2, -beta>
<200, 180>
<120, ??>

do we have to find the angle for that last vector ?

Answer 9

The triangle is drawn

Answer 10

In mechanics they mostly draw the triangle on the line like this:

Answer 11

ok, so we need the angle. what is it ?
