A civil engineer must design a wheelchair-accessible ramp next to a set of steps leading up to a building. The height from the ground to the top of the stairs is 2 ft. Based on ADA codes, the slope must be 1:12 or less. Slope is equal to the rise of the ramp divided by the run of the ramp. Using the ADA code, what is the minimum allowable length of the ramp base?

Answers

Answer 1

Answer:

24 ft

Explanation:

The inclined plane can be used to form a right-angle triangle with the slope of 1/12. Using the equation for slope, we can estimate the lowest possible length of the base of the ramp:

slope = height/ramp base

1/12 = 2/ramp base

Therefore: ramp base = 2*12 = 24 ft.

Thus, the lowest possible length of the base of the ramp is approximately 24 ft.

You are seated in the drivers seat of your parked car, preparing to drive. You must properly fasten your seat bely

Answers

That's a true statement

Answering the question, if you are seated in the driver’s seat of your parked car, preparing to drive, you must properly fasten your seat belt. This statement is true.

It is required of both the passengers and the driver to wear seat belts. It is illegal in most countries if not all for anyone to operate a vehicle unless all the passengers are wearing a seat belt.

Further Explanation

Also, the use of seat belts varies from state to state in the United States and the laws are classified into two major parts: primary and secondary.

The primary seat belt laws enable officers of the law to fines a driver or passenger that fails to wear the seat belts while secondary seat belts laws allow officers to issue a ticket for drivers only when another traffic offense is committed by the same driver.

Wearing seat belts is very important because it saves lives.

Seat belts help to minimize injuries in case of an accident and protect the driver and passenger. Also, failure to wear seat belts could result in Head and spine injuries if an accident occurs.

Therefore, If you are seated in the driver’s seat of your parked car, preparing to drive, you must properly fasten your seat belt.

ATV stands for All-Terrain Vehicle (ATV), a four-wheeler or quadricycle. ATVs have a powerful drive train with high and low gear ratios. This creates significant danger for the operator. The danger is that with its wide low-pressured knobby tires, the vehicle may wobble or bounce easily causing loss of control.
