Mechanical Engineering: Particle Equilibrium (5 of 19) Beam and Cable Under Tension

In this video I will calculate the force of a cable under tension.

Next video in the Particle Equilibrium series can be seen at:

T1, T2, and T3 are in equilibrium and thus the system is static. that being said why would there be a non-zero resultant force with non-zero x, y components?

This is a good example of summing of forces (using the vertical and horizontal components) on a system in a non-equilibrium state. Thank you.

Because this is a static problem, the reactionary force would have to be of the same magnitude but in the opposite direction? Therefore, F-reactionary-x=-41.4 and F-reactionary-y=32.1 lbs? Otherwise, the two equations you wrote for Fx and Fy would be incorrect(since 41.4 does not =0 and -32.1 does not =0).

[snobphantom]

Sir, Why did not you use tan-1(-32.1/41.4) to find phi? Isn't minus sign important?

[playfun]

Wait... Is the axial force of the beam being neglected?

[rachealmulenga]

Instead of equating the fx and fy to zero what are we supposed to do

[yeanbasch]

Its like paint a Circle to firgure out the degree

[AL-knyx]

If the resultant force is not zero how can this system be static?

yo man whats up with the 120 cm and 80 com did you forget those lol jk but seriously?
