Mechanical Engineering
A vertical load P is applied at the center A of the upper section of a homogeneous
frustum of a circular cone of height h, minimum radius a, and maximum radius b.
Denoting by E the modulus of elasticity of the material and neglecting the effect
of its weight, determine the deflection of point A.
1) neglecting the effect of its weight only due to p
2) consider the effect of its weight (p+w)

What is the ratio between camshaft and crankshaft of 6 cylinder inline engine?
Mechanical Engineering
The internal energy of a fluid is initially 18kJ. The internal energy of the fluid is increased to 76kJ by a non-flow thermodynamic process during which 50J of work was done. Determine the magnitude and direction of the heat energy transfer across the system during the process.

A gas is pumped into an empty cylinder of volume 0.08m3 until the pressure is 6MPa. The temperature of the gas is 500C. If the gross mass of the cylinder increases by 5.3kg when the gas has been added find the value of the characteristic gas constant.
Mechanical Engineering
A quantity of gas in a cylinder occupies a volume of 0.9m3 at a pressure of 360kPa. A piston within the cylinder compresses the gas, according to Boyle’s Law until the gas volume is 0.35m3. If the area of the piston is 0.05m2 calculate the force on the piston when the gas is compressed.

How much heat energy is required to change 2.8kg of ice at 230K into water at 323K?
Mechanical Engineering
Two companies A & B, manufacture the same commodity. Company A uses a mechanized process, and company B relies mainly on manual labor. The fixed cost is $ 40,000 per month for A and $ 15,000 per month for B. The directly varying cost is $ 14 per unit for A and $ 52 per unit for B. The selling price is $ 85 per unit for each company. a) At what volume of production are the unit costs of the two companies identical? b) How many units must each company sell each month merely to avoid a loss”
