The annual income from the mine is P100,000 and the life of the mine is 20 years. Find the price that an investor is willing to pay for the mine if he considers that money is worth 5% and if he is to accumulate a sinking fund at 6% in order to replace the capital he invested.
Consider the truss system shown in Fig. 2 modelled by three elements. The element numbers are shown in brackets. The node numbers are as indicated in the figure. Suppose that all the trusses have a cross sectional area of A = 0.1 m2 and Young’s modulus E = 70 GPa. Determine the displacements at all the nodes if the force P = 2000 N. The length L = 2 m.
The solid compound shaft, made of three different materials, carries the two torques shown. (a) Calculate the maximum shear stress in each material. (b) Find the angle of rotation of the free end of the shaft. The shear moduli are 28 GPa for aluminium, 83 GPa for steel and 35 GPa for bronze.

Determine the maximum torque that can be applied at 1.0 m from the right end of the shaft, without causing excessive rotation.
1. Consider a NSW with a downstream-upstream temperature ratio of 3.5 what is the mach number upstream and downstream of the shock? Show your solution.
2. The flow just upstream of a NSW is at SSLC and the mach number downstream is 0.6152 determine the pressure, temperature, density, velocity, and the total pressure and temperature. Show your solution
3. The mach number behind of a NSW is 0.4752
What is the mach number in front of the wave and the pressure ratio across the shock? Show your solution.
To develop an oil well containing 2,000,000 barrels of oil required an initial investment of PhP 30,000,000.00. In a certain year, 400,000 barrels of oil were produced from this well.
The total gross income of the oil company is PhP 34,000,000.00 for the particular year, and the taxable income after talking all deductions, except for depletion, is PhP 14,100,000.00. Determine the allowable depletion allowance for the year.
tdx/dx = 6t(e^ 2t) +x(2t-1)
Help me for the solution of this problem:
What should be the maximum dimensions of a rectangular open box of a given volume V?
Can anyone help me how to calculate the zero moments in the questions?

A ship is traveling at a speed of 20 knots. (A knot is a nautical mile per hour, a nautical mile being approximately 1.1516 statute mile of 5280 feet each.) When directly opposite a target it fires a gun whose projectile has a velocity of 2000 feet a second. At what angle with the direction of motion of the ship must the gun be pointed in order to hit the target?
