What can engineers do to prevent structures from collapsing during earthquakes

Physics
1 answer:
vredina [299]3 years ago
3 0

Explanation:

1. The structures should be made with good quality steel and concrete so that they can bear load and deformation.

2. Buildings should be made laterally strong so that they can overcome dominant lateral forces.

3. In High seismic activity areas devices such as energy absorbers should be used. Base isolation must necessarily be done.

4. Use of hybrid Fiber Reinforced Concrete to increase the toughness of a structure in a Moment Resisting Frame. Moment resisting frames are frames that resist moment of any devices.

<h3>What is atom?</h3>

Atom is the smallest unit of the element. Different elements have different size atoms and same element have same size atoms.

James Chadwick tracked down the neutron in 1932 and was conceded the Nobel Prize for science in 1935  held in a German prison camp for all of World War 1, he driven the British gathering inside the Manhattan Extend, in which the UK and Canada maintained the USA's World War 2 effort to build the world with nuclear bomb.

Chadwick and Rutherford were the first scientists who measured the nucleus radius using the alpha particles. He did Gold foil experiment to find the size of nucleus.

The contributions are present in the modern atomic model. They are: All matter consists of atoms. Atoms of the same element are the same in size and atoms of different elements are different. Atoms combine in whole-number ratios to form compounds.

A 56.0 kg bungee jumper jumps off a bridge and undergoes simple harmonic motion. If the period of oscillation is 11.2 s, what is
andre [41]

Answer:

2.80N/m

Explanation:

Given data

mass m= 56kg

perios T= 11.2s

The expression for the period is given as

T=2π√m/k

Substitute

11.2= 2*3.142*√56/k

square both sides

11.2^2= 2*3.142*56/k

125.44= 351.904/k

k=351.904/125.44

k= 2.80N/m

Hence the spring constant is 2.80N/m
