Please write at least two paragraphs in your own words how a suspension bridge works. List all sources used. Thank you very much
Bumek [7]
Before description, set the picture of a suspension bridge as "<span>Gate Bridge or Brooklyn Bridge" which is quite famous so you would probably know about it.

In this type of Bridges, they are </span><span>suspended the roadway by cables, ropes or chains from two tall towers. That towers support the majority of the weight as compression pushes down on the suspension bridge's deck and then travels up the connection (cables, ropes or chains) to transfer compression to the towers. The towers then dissipate the compression directly into the earth.
Suspension cables </span><span>receive the bridge's tension forces. These cables run horizontally between the two far-flung </span><span>anchorages

Hope this helps!</span>

Which statement BEST compares the force of gravity on a school bus on a school day and a weekend? *
inna [77]

Answer:

(A) The force would be lower on the school day than the weekend.

Explanation:

In  a  school  day  the  bus  is  on  the  road  travelling  with  kids.  But  in  a  weekend  it  is  parked.  When  a  object  stays  still  that  means  the the  force  which  is  working  on  the  earth  by  the  bus  is  equal  to  the  force which  works  on  the  bus  by  the  earth. we  can  understand  it  clearly by,  Newton's second law of motion.  

This pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.  so  as  it  is  when  it  is  balanced  it  is  not  moving.

And  on  a  school  day  the  bus  is  moving  so  it  has  a  force  pulling  itself  forward .  so  it  means  that  the  force  which  the  bus  has  is  greater  than  the  gravitational  force.
