The modifications that are implemented after Tacoma bridge disaster are added trusses and openings below road decks to decrease oscillations.
<h3>Why Tacoma Bridge disaster occurred?</h3>
While marching, the natural frequency of the vibrations of marching soldiers matched up with the resonant frequency of the bridge. This resulted in the collapsing of the bridge in seconds.
Because of the disaster of the Tacoma Narrows Bridge, the bridge was strengthened by adding trusses as well as openings below road decks so as to decrease vibrations caused by running vehicles on the bridge.
Thus, the modifications that are implemented after Tacoma bridge disaster are added trusses and openings below road decks to decrease oscillations

Answer:
There are equal parts reactants and products.
Explanation:
When a system is in a chemical equilibrium, the rate at which the forward reaction occur is the same as the rate at which the reverse reaction occurs. This system is said to undergo a reversible reaction. The concentration of the reactants and products do not change, i.e are constant.
In a chemical equilibrium, the reaction continues in both directions but at the same rate.
Therefore the statement that is a misconception about a system in chemical equilibrium is 'There are equal parts reactants and products'.
Answer:
Resultant velocity will be equal to 6.10 m/sec
Explanation:
We have given a motorbike is traveling with 5 m/sec in east
And a current is flowing at a rate of 3.5 m /sec in north
We know that east and north is perpendicular to each other
So resultant velocity will be vector sum of both velocity
So resultant velocity 
So resultant velocity will be equal to 6.10 m/sec
