Problem 1: A small truck with a center of gravity at X=2.5ft and Y=6ft is traveling on a circular path of radius R=400ft and e=4% where e=rate of superelevation. Determine the maximum safe speed to avoid both slipping and overturning.
Problem 2: School buses are claimed to be a traffic blessing, especially during the morning peak hours. Assuming that the morning trip is composed of: 70% work trips and others 20% educational trips using school buses carrying 60 students each (1 bus=2.5 EPC) 10% other purposes Also assuming that the replacement for school bus is a " ride sharing minibus".
An engineer is required to survey a nonrectangular plot of land but is unable to measure side UT directly (see Figure 2.11). The following data are taken: RU=130.0m, RS=120.0m, ST=90.0m, angle RST= 115 degrees, and angle RUT= 100 degrees.Calculate th..
An underground limestone mine with production of 12,000 tons/day will use trucks for the main haulage between an ore pass and a hoist skip pocket. The hauling distance is 5500 ft. The main haulage drift is horizontal and is 12.5 ft wide and 12.5 f..

The barrel has an inner diameter of 4ft. Neglect its wall thickness. Assume that only the hoops resist the water pressure. Note: Water develops pressure in the barrel according to Pascal's Law, p=62.4 lb/ft^2, where z is the depth from the surface..
You will be analyzing the frame below,which has the same properties as the previous homework:
First consider highway driving. Assume a constant velocity of 27 m/s (60.4 mph) on level ground. Under these conditions the efficiency of the engine plus auxiliaries is 30 percent and the efficiency of the drivetrain is 85 percent. What is the fuel c..
A Bonda portable generator is powering a small travelling fridge (120V) in your RV and consumes 125 watts. The efficiency of the generator's gas motor is 23% and the electrical portion (power head) is more efficient at 91%. If white gas weighs 6.073 ..
