A concrete block of mass 225 kg hangs from the end of the uniform strut

The system in the figure is in equilibrium. A concrete block of mass 225 kg hangs from the end of the uniform strut of mass 45.0 kg. For angles Ф = 30.0° and θ = 45.0°, find (a) the tension T in the cable and the (b) horizontal and (c) vertical components of the force on the strut from the hinge.

God bless ur channel, you are a lifesaver

[@Hnelson1999]

you're saving my physics mark.

[@guggystyle]

I'm glad to hear that!

[@nachoburritto]

You're an absolute legend. Thanks a bunch mate

[@guggystyle]

You're welcome!

[@wolfgangschoenberger888]

y'all are the best. Thanks a bunch

[@bb-gm8dd]

Why did you not use Tcos(theta) when you were finding the horizontal components?

[@j.s.s9108]

I really apreciate it man thanx alot 💙💙

[@guggystyle]

+. No problem!

Where is the strut length cosine

[@bossvalverde]

The best thank you!

[@parhanakbar4034]

Terimakasih, penjelasan kamu mudah dipahami

[@useronioncrisis]

Hello, why did we cancel the length?

[@jake.r.stroup]

4:48 clockwise* not ccw (?)

[@xolanibooi5356]

I am sending an email soon happy with the results

[@Jinanmomen1]

thankuthankuthankuthankuuuu

Look at this different approach of solving the problem. What I dont understand is, why he used also cos of the angles. You were only using sin of the angles.
