Q. I started my engineering career when I was 22. After 10 years, my age was the sum of the digits of my birth year. When was I born?
Solution:
Let’s denote the birth year as 19XY.
Age when starting career: 22 years
After 10 years: 22 + 10 = 32 years
Sum of birth year digits: X + Y = 3 (since 19XY, X + Y = 1 + X + Y = 3)
Solving X + Y = 3 gives possible values for X and Y.
For example:
If X = 1, Y = 2 (birth year 1922)
If X = 2, Y = 1 (birth year 1921)

Q. The sum of the ages of two engineers is 60. One engineer is twice as old as the other. How old are they?
Solution:
Let’s denote their ages as E1 and E2.
E1 + E2 = 60
E1 = 2 * E2
Substitute E1 from the second equation into the first:
2 * E2 + E2 = 60
3 * E2 = 60
E2 = 20
E1 = 2 * 20 = 40
Therefore, one engineer is 40 years old, and the other is 20 years old.

Q. An engineer is designing a cylindrical water tank that needs to hold 1000 liters of water. The tank’s height is twice its radius. What are the dimensions of the tank?
A. Radius r≈5.6meters & Height h≈11.2 meters
Solution: Let’s denote the radius as r and the height as h.
h = 2r (height is twice the radius)
Volume of cylinder = π * r^2 * h = 1000 liters
Convert liters to cubic meters (1 liter = 0.001 cubic meters)
Solve the equation to find the radius and height of the tank.

Q. An engineer is calculating the efficiency of a new solar panel system. If each panel generates 500 watts of power and there are 20 panels, how much power in kilowatts does the entire system produce?
Solution: Let’s denote the power generated by each panel as P and the number of panels as N.
Total power = P * N / 1000
Total power = 500 * 20 / 1000 = 10 kilowatts
Therefore, the entire system produces 10 kilowatts of power.

Q. An engineer needs to calculate the pressure exerted by a hydraulic system. If the force applied is 5000 newtons and the area over which it is applied is 2 square meters, what is the pressure in pascals?
Solution: Let’s denote the force as F and the area as A.
Pressure = Force / Area
Pressure = 5000 N / 2 m² = 2500 pascals
Therefore, the pressure exerted by the hydraulic system is 2500 pascals.

Q. An engineer needs to design a staircase with steps that rise 15 centimeters each and run 30 centimeters each.
If the staircase needs to reach a height of 3 meters, how many steps are required?
Solution: Let’s denote the number of steps needed as N.
Total height = Step height * N = 15 cm * N = 300 cm (since 3 meters = 300 cm)
Number of steps, N = Total height / Step height = 300 cm / 15 cm = 20 steps

Q. An engineer is designing a suspension bridge with cables that can support a maximum load of 500 tons. If each cable is rated to withstand a maximum tension of 1000 tons and there are 4 cables supporting the bridge, how much weight can each cable safely support?
Solution: Let’s denote the maximum weight each cable can support as W_cable.
Total maximum tension capacity = Number of cables * Maximum tension per cable
W_cable = 500 tons / 4 cables = 125 tons
Therefore, each cable can safely support up to 125 tons of weight.
