A213-BSIE 20 Directions: Solve the following problems completely. Minimize erasures, no short-cuts. Save and turn-in, in PDF file. Write the problem on your answer sheets. 1. An object whose mass is 10 kg weighs 95 N. Determine, (a) The local acceleration of gravity, m/s (b) The mass, in kg, and the weight, in N, of the object at a location where g=9.81 m/s?. 2. The weight of an object on an orbiting space vehicle is measured to be 42 N based on an artificial gravitational acceleration of 6 m/s?. What is the weight of the object, in N, on earth, where g=9.81 m/s?? 3. The storage tank of a water is nearly spherical in shape with a radius of 30 ft. If the density of the water is 62.4 Ib/ft?, what is the mass of water stored in the tower, in Ib, when the tank is full? What is the weight, in Ibr, of the water if the local acceleration of gravity is 32.1 ft/s?? 4. A lunar excursion module (LEM) weighs 1500 Kgr on earth where g=9.75 mps2. What will be its weight on the surface of the moon where g=1.70 mps?. On the surface of the moon, what wil be the force in Kg and in Newtons required to accelerate the module at 10 mps?? 5. The mass of a fluid system is 0.311 slug, its density is 30 lb/ft and g=31.90 fps². Find (a) the specific volume, (b) the specific weight, and (c) the total volume.

Example 1-2 In order to save on imported fuel, Philippine researchers propose blending diesel with coconut methyl ester (CME) or cocodiesel derived from trans-esterification of high grade coconut oil. The mixture of these two compounds is called CME-Diesel Blend. The density of CME is 785 kg/m while that of diesel is 885 kg/m. If a 150 L fuel tank of a truck is fully filled with CME-Diesel Blend with a density of 840 kg/m, how many kilograms of CME and diesel are in the tank?
