The two structural members, one of which is in tension and the other in compression, exert the indicated forces on joint o. determine the magnitude of the resultant r of the two forces and the angle θ which r makes with the positive x-axis. the angle θ is measured counterclockwise from the positive x-axis.

R = 3.606 KN, θ = 24°

Explanation:

Resolving the forces to the x-direction

Rx = 3cos60 + 2cos30

= 1.5 + 1.732 = 3.232 KN

Resolving the forces to the y-direction

Ry = -3sin60 + 2sin30

= -2.6 + 1 = -1.6 KN

Getting the resultant of the two forces

R =

Substituting the values of Rx and Ry, we obtain

R = 3.606 KN

tanθ = Ry/Rx = | -1.6/3.232 |

Then we have θ = 24°

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
