Since the bridge and all segments of it are static, the sum of the torques acting on any portion of the bridge you choose is zero for any pivot <span>point you may choose. See if you can find a rigid portion of the bridge and a wisely chosen pivot to which you can apply this powerful fact.
</span>Consider the triangular portion shown in bold and let x be the pivot. (This choice eliminates the torques
due to the tensions in the beams that attach at
point x.) Find the torques on this left hand
triangle (which can be considered a solid piece
because of the connections). Remember that
counterclockwise torque is positive. Assume
that the horizontal segment above is being
stretched, so that the force that the tension in
this segment exerts on the bold triangle is
directed to the right.
Express the torque in terms of T, L , and Fp.
Answer in terms of T and L :
Tt = (TL.sqrt 3) / 2
Summation Tx = -LFp - T sqrt[L^2 - (L/2)^2]
The negative value of the tension shows that the segment is actually under a compressible load. <span />
Some types of storage tanks are exempt from the federal regulations on USTs, including
: A) tanks that store heating oil burned on the premises.
<h3>What are Underground Storage Tank Systems?</h3>
Underground Storage Tank systems are tanks along with the underground piping that has at least 10% of their total volume underground.
Some of the storage tanks that are exempt from the federal regulations on USTs are;
- Farm and residential tanks of 1,100 gallons or less capacity holding motor fuel used for noncommercial purposes.
- Tanks storing heating oil used on the premises where it is stored.
- Tanks of 110 gallons or less capacity.

We know that the average speed is simply the ratio of the
total distance travelled over the total duration of the trip.
total distance = 500 mi + 380 mi + 600 mi
total distance = 1,480 mi
total time = 10 h + 8 h + 15 h
total time = 33 h
So the average speed is therefore:
average speed = 1,480 mi / 33 h
<span>average speed = 44.85 mi / h</span>
Thank you for posting your question here at brainly. Below is the answer:
m = 80 kg
R = 6.4 x 10^6 m
Earth completes one rotation in 24 hours
Thus, T = 24 x 3600 s
Centripetral acceleration is given by
ac = w^2R
ac = (2 pie/T)^2R
ac = (2 pie/T)^2R = 4 pie^2/(24 x 3600)^2 x 6.4 x 10^6
ac = 0.034 m/s^2
