We have not learned singularity functions and the professor said only double integration should be used if these questions appeared on a exam. Also, the slopes should be equal at that very point since its identical on both sides. I'm just unclear as of why I'm getting completely different...

Thanks for replying. Yes I know you have to integrate over the entire beam. I used matching conditions since if I make a cut at x=L, I know the deflections will be similar at that point for each side. Between 0 and L, I solved for the constants and got zero since its at a fixed end. For C3 and...

When using the double integration method to solve for deflection, do you simplify the integral before integrating or do you just integrate it? When i tried it with simplifying and without simplifying, I get a different value for the constant which results in different answers. For example in...

Ok perfect. Thanks so much.

Is the maximum bending moment and maximum shear stress an absolute value? For example, when drawing out a bending moment diagram say if I get -400 kNm at one point and 300 kNm at a different point. If these values are the maximum/minimum points on my diagram would 400 kNm be considered as a...

Hey, How would you realize if a shaft can resist a torque or not given an allowable shear stress and allowable angle of twist. Can I use the factor of safety? Thanks.

Thanks for replying. Does that mean my answer is correct?

Homework Statement In the attachment. Need to calculate azimuth of BC. Homework EquationsThe Attempt at a Solution I don't understand why the azimuth of AB would be given as 126 degrees when it is almost a complete revolution of 360 degrees. I calculated the back azimuth which would be...

Alright thanks for the help.

Just to clarify, does the "a" represent the length from the timber truss parallel to the grain?

So 100 x 150 -mm is referring to width x depth, thus the cross section would be a x width?

Hey thanks for replying. The horizontal force of the bottom chord would be equal to the tension of AB which would be 12kN. So summing the forces in the y-direction, ∑Fy = V = 12 kN. (I'm not sure if this value is correct.) I still do not understand the cross sectional area. The question states...

Homework Statement Member AD of the timber truss (shown in attachment) is framed into the 100 x 150 mm bottom chord ABC as shown in the insert. Determine the dimension "a" that must be used if the average shearing stress parallel to the grain at the ends of chord ABC is not to exceed 2.25...

Wow thank you. It's been a long day. Can't believe i missed that. Lol

Homework Statement (42°12'13'')+(59°56'15'')+(257°51'35'') Homework EquationsThe Attempt at a Solution 42°12'13'' 59°56'15'' 257°51'35'' -------------- 358°228'63'' +3° +1' -60'' --------------- 361°229'3'' -180' --------------- 361°49'3'' The answer is 360°0'3'' Where did I go wrong?
