An axle weight study on a section of highway gave the following data on axle load distribution. Determine the truck factor for this section of highway. Assume
SN = 4
and
pt = 2.5.
3. A 10L volumetric container weighing 6.2 kg has been packed with gravel by the required method, and then the total weight is 21.3 kg.
a, Calculate the bulk density of gravel.
b, If water is filled into the container, the total weight becomes 25.9 kg after 24 hours. Calculate the apparent density and porosity of the gravel.
The truck drives on a horizontal road with a constant velocity. It eventually halted by a set of crash barrels. The number of barrels and sand within the barrels are arranged in such a way to decelerate the truck at a constant rate. Four test runs are performed where the velocity and mass of the truck are varied. In each of the following situations, the barrels stop the truck in the same amount of time.
Which has the a. least force, b. greatest force.
