Problems like this that involve 3 dimension forces is partly why most people fail Structural Analysis the first time they take it. Its just the complicated nature of the subject that make it an exceptional challenge.
Good day po Engr. Moment of a force about an axis namn po request ko. Hehe. And any topics sa engineering mechanics (statics) by Hibbeler. gusto ko po kasi talaga mamaster Yung Cartesian approach niya sa pagsolve ng mga related problems kasi napapadali Yung pagsolve. Thank you po and God bless!
Sir, why is it in the summation of Fx, we use sine? Don't we use cosine for x-component? Or did we use sine because of the concept of sine law? Im referring to the first problem sir.
we use cos for x-component, the given here is the angle of the line with respect to the Y-component so he use the sine, BUT we can use the Cos to avoid confusion, sin(30) is equals to cos(60) BUT NOT cos(30), angle has to equates to 90 degree, 30-60, 45-45, 20-70, 14-76
GOOD EVENING PO SIR Pa shout out po. SIR Engr. Abat! ASHAROOK A. ABOBAKAR, 2nd year CE student from NOTRE DAME UNIVERSITY OF COTABATO CITY THANK YOU PO SIR MARAMI PO TALAGA AKO NATUTUNAN SAINYO THANKYOU PO TALAGA AND MORE POWER AND STAY SAFE PO PALAGI SIR PARA MORE VIDEOS TO COME HEHEHE GOD BLESS!
Good day po sir, in the 2nd problem how do you know that the summation of Fx and Fy are zero? May I have a complete solution? It is hard to understand how the forces are the same if the lengths are equal. Thank you!
hina talaga imagination ko sa free body diagram sir. Sir, sa Example 1, di naman po 90 degrees yung itsura ng angle sa x bat po cinonsider niyong 90 degrees? salamat po
Sir about sa second problem, ang tangent po na ginamit (TOA) is only applicable for right triangles. so ibig sabihin po malabo na ang opposite side ng 49.1 degrees is 600mm dahil hypotenuse yung 600mm so dapat ang opposite angle nya is 90 degrees. paano po yun sir please help.
Bro im having difficulties with thermodynamics whats ur status rn? Im currently in bs aicraft maintenance 3rd yr i hope we could discuss and share our different knowledge to improve bout the subject.. thanks
