What is the required force to pull a metal container weighing 36,000 lbs up a concrete ramp that is 6 ft high and 24 ft long?

To determine the required force to pull the metal container up the ramp, we can apply the concept of mechanical advantage provided by the ramp's angle of elevation. The force required to move the container along the ramp depends on the angle of incline and the weight of the object.

First, we must find the ramp's angle using the height and base. With a height of 6 ft and a length of 24 ft, we can use the sine function. The ramp creates a right triangle in which the height is opposite to the angle, and the length of the ramp is the hypotenuse.

By calculating the sine of the angle:

• Sine(theta) = height / hypotenuse = 6 ft / 24 ft = 0.25

Next, we can find the angle of inclination. However, for the purpose of calculating the force, we will consider the relationship derived from trigonometry. The required force to pull the weight up the ramp can be found by incorporating the sine of the incline, which accounts for the gravitational force acting against the pull when moving the container up the ramp.

The required force (F) can be calculated using the formula:

• F = weight * sin(theta)

Thus:

• F = 36
