Question

Please help me solve the following problem. Three forces are applied to a bracket as shown (click to see picture). The directions of the two 150N forces may vary but the angle between these forces us always 50*. Determine the range of values of the angle (a) for which the magnitude of the resultant of the forces acting at A is less than 600N.

Answer 1

the (a) is an angle?

Answer 2

yes

Answer 3

it is a 90 degree angle

Answer 4

A is

Answer 5

be right back... i have to check my solution...

Answer 6

just to complete what i started... solve for angle a first when resultant of given forces equals 600N...
Consider the resultant of 2 equal forces of 150N spaced by 50\(^\circ\)... applying arrow-to-tail (see the drawing)
... a rhombus is formed (shown also 2 obtuse triangles)
