Question

what's the angle?

Answer 1

of the dangle?

Answer 2

of the bottom half. it's confusing, F_2...45 and 60 from x axis? y axis? it's not clear to me

Answer 3

these angles aren't suppose to be directional angles (alpha, beta, gamma) i don't think...

Answer 4

the top for sure aren't directional angles

Answer 5

This diagram is confusing... which angles do you need to find out?

Answer 6

Do you get that the angle at the top right indicated as 45 degrees is for the z plane?

Answer 7

i need to know what these angles are. if it's the angles of the projection of the force vector in xy plane or if they are directional angles

Answer 8

i understand the top, it's already solved and verified. here's the problem:
determine the magnitude and coordinate direction angles of the resultant force acting on the bracket. so i did that for the top and verified by finding the absolute value of the components and the result is 450

Answer 9

they should be angles of the projection of the force vector judging from the top image.

Answer 10

i know how to solve the bottom, but i would need to know if they are directional angles or angles of projection

Answer 11

right but it wouldn't make sense since 45+60>90

Answer 12

What do you mean by angles of projection?

Answer 13

The 45 degree angle is between the x-axis and the vector going to some direction that involves all 3 x,y,z axis.

Answer 14

It's possible because it's got three dimensions. If it was a flat plane, max is 90 degrees, but your max shouldn't be 90 since there are 3 (x, y, z)

Answer 15

The object is dangling As EdgeOfThe Earth has pointed out so it would need all three XD

Answer 16

projection is transferring the 3d vector in xy plane making it 2d. so if it is the angle of projection and looking at the pic, the angles are from the x and y axis so it would have to be equal or less than 90
