Answer:

<em>c. The tension in the cord connected to the truck is greater than 1200 lb</em>

<em>e. The normal force between A and B is 1200 lb.</em>

Explanation:

The correct question should be

A 1000 lb boulder B is resting on a 200 lb platform A when truck C accidentally accelerates to the right (truck in reverse). Which of the following statements are true (select two answers)?

A free body diagram is shown below.

The normal force between the the boulder and the platform will be the sum of the force, i.e 1000 lb + 200 lb = 1200 lb

For the combination of the bodies to accelerate upwards, then the tension must be greater than the normal force, i.e T > 1200 lb

Alexandra [31]

It was determined by the forensic engineers that the historic collapse of the Minneapolis Interstate Bridge was due to design and construction flaws. It led to the collapse of the structure.

<h3>What is the Minneapolis Interstate Bridge?</h3>

The Minneapolis Interstate Bridge is a well-known bridge that was constructed in Minneapolis city in 1967.

It has been demonstrated that the collapse of this bridge constructed in Minneapolis was due to its inadequate load capacity.

In architecture, it is fundamental to measure the amount of weight that a structure (in this case, a bridge) can sustain in a given period of time.
