A structural steel column with Fy = 250 MPa
having an unbraced length of 3m is to carry a total axial load of 1800 kN. Which of the following sections is most economical (lightest ) for the given loads. The comumn is hinged at both ends.
Section A: Area = 13,800mm2 Ix= 293.63 x106mm4Iy= 67.59 x 106mm4
SectionB: Area = 11,550 mm2 Ix=177.04 x 106mm4Iy=39.14x 106mm4
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.
The given two-parameter family is a solution of the indicated differential equation on the
interval (−∞,∞). Determine whether a member of the family can be found that satisfies the
initial conditions.
y = c1e^x cos x + c2e^x sin x; y" − 2y' + 2y = 0,
i. y(0) = 1, y'(π) = 0
ii. y(0) = 1, y(π) = −1

The first cost of a certain machine is P90,000. After 8 years it will have a salvage value of P18,000. Compute the book value at the end of 3 years by using the sum of the years digit method.
xy' = y + 2 √xy
A company has a certain number of machines of equal capacity that produced a total of 180 pieces each working day. If two machines breakdown, the workload of the remaining machines is increased by three pices per day to maintain production. Find the number of machines?
(xy + (y/x) + (3/x) -2) dy + y2 dx = 2(1+(y/x))dx
Geometrical Application
Find the eq. of the curve such that the x-intercept of the tangent line at any pt. (x, y) on it divided by the square of the ordinate is a constant.
