Question 1 1.1. Use EASYEDA to Design the following electrical circuit, and determiner the voltage across resistor 1 to resistor 5. (7) 1.2. From 1.1 one use EASEDA to design the equivalent circuit and measure the voltage across the R equivalent. (3) [10] Question 2 2.1. Use EASYEDA to Design the following electrical circuit in figure 2, and determiner the voltage across resistor 1 to resistor 6. (7) 2.2. From 2.1 one use EASYEDA to design the simplified circuit and measure the voltage across the R total. (3) [10] Total 20

The maximum actuating force on a double short shoe external drum brake illustrated in figure 1 below is 3 kN. If the coefficient of friction for the shoe lining is 0.3. 1.1 Determine the torque capacity of the brake for clockwise rotation of the drum. (11) Hint 1: Note the distance between the shoe and the pivot is not ignorable. Hint 2: Consider both shoes in your analysis. 1.2 Draw the forces acting on each shoe. 

A 10ft long horizontal through has ends in the shape of equilateral triangles. The sides of the triangle are 6ft in length. If water is being poured inside the through, find a mathematical model that expresses the volume of the water as a function of its depth

if the % increase in power required for a helicopter to hover at an altitude above sea level is 6% higher that required to hover at sea level with the same figure of merit, determine the altitude. assume that the density change is 8% per km.

In the manufacturing of an $8 000 car, how much do you estimate is spent on direct labor?

The average Japanese autoworker makes around $8 to $10 per hour and each car at Toyota has about 30 direct labor hours in it. If the average US autoworker makes $20 per hour, how many worker-hours of direct labor are in the typical American car?

If the rolls for the cold-rolling mill that produces the sheet metal used in the car cost $ 300 000, how is it that the cars can still cost less than $10 000?
