figure 49

QUESTION: Modify the design of the 7 segment display multiplexing system in figure 49 to accommodate two additional digits.

A big group of students, starting a long journey on different set of vehicles need to fill petrol in their vehicles.

As group leader you are required to minimize the time they spend at the petrol pump to start the journey at the earliest. You will be given the quantity of petrol (in litres) that can be filled in each vehicle. There are two petrol vending machines at the petrol pump. You need to arrange the vehicles in such a way that they take shortest possible time to fill all the vehicles and provide the time taken in seconds as output. Machine vends petrol @ 1litre/second.

Assume that there is no time lost between switching vehicles to start filling petrol.

The two-member structure is connected at C by a pin, which is fixed to BDE and passes through the smooth slot in member AC. Suppose thatF1 = 550 lb . (Figure 1)

Determine the x and y components of reaction at point A using scalar notation.

Express your answers using three significant figures separated by a comma.

Determine the y component of reaction at point Dusing scalar notation.

Express your answer to three significant figures and include the appropriate units.

Determine the x and y components of reaction at point E using scalar notation.

Question 1
Write a program that reads from the user the height and radius of a cylinder, and then outputs the area of this cylinder. The area of the cylinder is calculated using the formula:
A=2*π*r*h+2*π*r2, where π = 3.14.
Sample run:
Enter the radius of the cylinder: 8.2
Enter the height of the cylinder: 9
The area of the cylinder is 885.75

Question 2
Write a program that reads the name, weight and height of a patient. Then the program outputs if the patient is under weight, average or over weight based on the following formula:
BMI = weight/height2
BMI < 20: Underweight
BMI between 20 and 25: Average
BMI > 25: Over weight

Sample run 1:
Enter your name: Samar
Enter your weight in kg: 70
Enter your height by meters: 1.67
Samar is overweight

Sample run 2:
Enter your name: Rola
Enter your weight in kg: 48
Enter your height by meters: 1.5
Rola is average

Sample run 3:
Enter your name: Rami
Enter your weight in kg: 85
Enter your height by meters: 1.88
Rami is underweight
