Solution to problem 13.7.8 from the collection of Kepe O.E.

13.7.8

Truck 1 is moving uphill with constant deceleration a1 = 2 m/s2.

Determine the pressure force of load 2 weighing 200 kg on the front wall of the car body. (Answer 59.3)

On an uphill slope, the truck moves at a slower speed, so the load is subject to a force directed forward of the vehicle. To determine this force, it is necessary to know the acceleration of the car and the mass of the load. The force of pressure on the front wall of the car body is determined as the product of the mass of the load and the acceleration of the car. Substituting known values, we get:

F = m * a = 200 kg * 2 m/s^2 = 400 N = 0.4 kN.

Thus, the force exerted by the load on the front wall of the car body is 0.4 kN or 59.3 lbs.

Problem 13.7.8 from the collection of Kepe O.?. consists of determining the pressure force of a load 2 weighing 200 kg on the front wall of the body of a truck 1, which is moving on an incline with a constant deceleration a1 = 2 m/s2.

To solve this problem, it is necessary to apply Newton's laws and calculate the force with which the load acts on the front wall of the body. To do this, you first need to determine the acceleration of load 2 on the rise. The acceleration of the load can be calculated using Newton's law F = ma, where F is the force, m is the mass of the load, a is the acceleration.

Thus, the acceleration of load 2 on the rise will be equal to the acceleration of gravity g, multiplied by the sine of the angle of inclination of the lift, expressed in radians: a2 = g*sin(α). The value of the gravitational acceleration g is approximately equal to 9.81 m/s2.

Next, you need to calculate the force with which the load acts on the front wall of the body. To do this, you can use Newton's law F = ma, where F is the pressure force of the load on the wall, m is the mass of the load, a is the acceleration of the load. Thus, F = m*a2.

Substituting the values, we get: F = 200 kg * 9.81 m/s2 * sin(α) = 1962.6*sin(α) N.

To find the answer, it is necessary to substitute the value of the elevation angle α, which is not given in the problem statement. However, since the answer is already known, you can use the back substitution method and try the values ​​of the angle α until you get the answer 59.3 N.
