How do you determine when a truss will fail?
(Yield Stress)
Answer:
If a truss buckles or overturns, it is usually because of the failure of an adjacent truss or its bracing. A steel truss in a fire may buckle and overturn because of expansion or weakening from the heat. Most truss failures are the result of broken connections. Photo 1 shows a set of parallel-chord wood trusses supporting a plywood floor deck.

When you are climbing a hill on a bike with different speeds, why does it seem like you are pedaling a lot to cover a short distance? What happens if you switch to a higher gear in hopes of not having to pedal as much?
It seems like your pedaling a lot because it takes more energy and is way slower than a regular road. It you switch to the higher gear it will make you go slower because it is made for going down hill or going high speeds and a lower gear will help you more cause its easier and it will make it go faster.
The reason why it seems you have to cover a short distance when pedaling up the hill is explained in Paragraph 2 below.
What will happen if you switch to a higher gear hoping you wouldn't pedal too much is explained in paragraph 3 below.
Bikes are usually configured in such a way that the mechanical advantage which is the ratio of output force to input force will increase when there is an increase in resistance like the question shows by climbing a hill.Now, since there is resistance from climbing the hill on the bike, it means that you must increase your effort by completing more revolutions since the bike tires itself would not complete that much revolutions required to counter the trade off distance.Finally, if you decide to switch to a higher gear it means it will become very difficult to pedal since you need power to do so.

How many 16ths are in 2 1/2
Consider steady, incompressible, laminar flow of a Newtonian fluid in an infinitely long round pipe annulus of inner radius Ri and outer radius Ro Ignore the effects of gravity. A constant negative pressure gradient _P/_x is applied in the x-direction, (∂P/∂x)=(P1-P2)/(x2-x1) where x1 and x2 are two arbitrary locations along the x-axis, and P1 and P2 are the pressures at those two locations. The pressure gradient may be caused by a pump and/or gravity. Note that we adopt a modified cylindricaloordinate system here with x instead of z for the axial component, namely, ( r, θ ,x) and (Ur, Uθ ,Ux) Derive an expression for the velocity field in the annular space in the pipe.
