First set which rotation is positive when taking the moment, in this problem I assumed clockwise moment as positive.

Given in the problem is 60 mm diameter. The 30 mm is the radius taken as half of the value of the diameter.

@@EngrRyeTutorials Pa gawa po vid sir about trusses pa ano kumuha ng angles at forces.

@@riiru33 magkaiba kasi ang shearing stress ng aluminum at steel, kaya nag solve tayo ng allowable load na kakayanin nila. Then we also consider the angle of twist, after that we select the lowest value which is the safe load na kakayanin both ng aluminum and steel and not exceeding the allowable rotation.

@@EngrRyeTutorials gets po sir thank you po

You're most welcome. Happy learning!

​​@@zakirhussainjokhio5478 P is equal to 3000 lbs (equal to 3kips), the force acting on the system at its end (steel and aluminum ) is 4P=12kips (tension) less P=3k kips (compression) on Bronze that gives you 9 kips

@@NoobCube248 statement po sa problem that the system is prevented from rotating. The force F is the force preventing the system to rotate and should be opposite of the direction of the given torque kaya sya assumed clokwise

You're welcome

@@salahudinali4620 3+1/2 lang po kasi naresolve na into concentrated force ang component ng UDL na nakainclined.

Btw 3+3/2 is still 4.5 po same lang.

kailangan po ba sa uniform loads na naka inclined is yung resultant gawing naka cos at sin?

@@salahudinali4620 yes po kasi nakainclined po sya

Inexpress lang po sa lowest term ang slope, though you can also use the actual length given sa problem

But that area is larger than that of using "b" so the mode of failure is higher on the thinner part of the key.

Actually applicable po both algebraic and trigonometric pero mas limited lang si trigonometric kasi sya may pattern na sinusunod (3 cases yung acos, asin at atan).

Depende po sa case, maaring panoorin ang paraan king paano magsolve ng Trigonometric Substitution sa link na ito: ua-cam.com/video/GA_OAt9Ljq0/v-deo.html

Depende po sa case, panoorin ang trigonometric substitution topic

Any Greek letter naman po pwede gamitin aside from theta, most books use theta lang kasi.

I'll manually input English subtitle for this part.

@@EngrRyeTutorials thank you please

I already uploaded the English subtitle for this.

I just used the calculator technique to solve for d using the shift solve function

Yes I am a Filipino. Thank you for watching my lectures.

You don't need pi for solving area of rectangle po, length times width lang i.e. 70b

Given po ang load na 4P sa figure and ang value ng P ay 3000 lb sa problem. 4(3000)=12000 lb

Sinubukan ko pong pagpalitin yung value ng Area sa AB and AC but both of them po exceeds 30 ksi sa value ng stress

Using the safe load P computed. Use sigma (normal stress) = P/A. By then you can show that it does not exceed the allowable 30 ksi normal stress.

To compute the Torque its force time distance po. Formula po yan.

Distance po ang 6 sa cosine then ang 3 sa sine, wag mo ipasok sa angle. Input ka ng close parenthesis after ng angle 56.3, it should go like this cos(56.3)*6 and sin(56.3)*3. Nasa labas dapat ng parenthesis ang 6 and 3, hindi sila part ng angle.

Diba sir gumawa po kayo ng FBD sa AB sa B po wala nang horizontal at vertical components?

May vertical and horizontal components po ang B pero since doon tayo nagtake ng moment sa B mismo magze-zero po sila. Considering FBD for member AB.

No need, it will just be cancelled out, regardless of mm or m. As long as it's consistent.

You're welcome po

The given weight is lb/ft meaning you have to multiply the weight by length to solve for the total weight. If the given is mass in kilogram or lb mass then that's the time you use the w=mg.
