Downtown New York to JFK Airport
First, the reaction force of the support is calculated Σ MA=0 eighty-three point three × 2.085+83.3 × 3.505+82.32 × *** × *** × 9.15+58.8 × 10.55-RB × 15.6=0
RB = 215.33kn (b support). Also: Σ Y = 438.42, RA = 223.09 (a support)
On the contrary, the tension of the upper part is negative and that of the lower part is positive. In civil engineering, the bending moment diagram is usually drawn on the tensile side of the member, and the sign may not be indicated on the diagram). For example, for a cantilever beam, when the beam end force is 2Kn, the beam length is 3M, the rigid fixed end bending moment is - 6kn · m, and the beam midspan bending moment is - 3kn · M
extended data:
bending moment diagram is a kind of diagram line, which is used to show the change of bending moment along the axis on each cross section of beam. The conclusion is as follows:
(1) in a certain section of the beam, if there is no distributed load, i.e. Q (x) = 0, from D to 178; M(x)/dx²= Q (x) = 0, m (x) is a linear function of X, and the bending moment diagram is an oblique line
(2) in a certain section of the beam, if the distributed load is applied, i.e. Q (x) = constant, then D & # 178; M(x)/dx²= Q (x) = constant, we can get that m (x) is a quadratic function of X. The bending moment diagram is a parabola(3) if fs (x) = DM (x) / DX = 0, there is an extreme value (maximum or minimum) of bending moment in a section of beam. That is to say, the extreme value of bending moment occurs on the section with zero shear force

after searching for a long time, I finally found the "Hope" card. Fortunately, I stayed at that time and was able to send it
in addition, there are free and paid newspapers in Chinatown of New York, and there are many similar advertisements on them for reference.

do you want to go to the state or it's a long way, or call a friend to pick you up
I don't know the price, you can ask a few more cars
when you come out of LaGuardia Airport, you can call these call companies. They all speak Mandarin Chinese. Their cars are metered. They will pick you up at LaGuardia Airport. If you tell them your flight number or airline name or exit number, they will receive you, Then tell them the flight number or airline name or terminal number of the plane you are going to take, and they can take you to your destination
at JFK Kennedy International Airport, you may need to take the light rail to your terminal. The light rail is circular and runs around several terminals. If you miss the station, you can take the light rail in the opposite direction
have a good trip.
it's too tight to transfer in three hours, so they have to take a taxi. Laguardi airport has no subway, only buses.
