- Henry Ford’s Model T was originally designed and built to run on ethanol. Today, ethanol (190-proof alcohol) can be produced with domestic stills for about $0.85 per gallon. When blended with gasoline costing $4.00 per gallon, a 20% ethanol and 80% gasoline mixture costs $3.37 per gallon. Assume fuel consumption at 25 mpg and engine performance in general are not adversely affected with this 20–80 blend (called E20). Solve, a. How much money can be saved for 15,000 miles of driving per year? b. How much gasoline per year is being conserved if one million people use the E20 fuel?a) Let R represent the reaction force at Support B. By releasing the beam at Support B and imposing a force R at Point B, the deflection of the beam consists of two parts,i.e. Part I- the deflection caused by MB ; Part II- the deflection caused by R Please treat R, w, h , L , E as variables in this step , the mathematical equation for the deflection at Point B caused by R ( Part II) can be written as (Hint : to input equation R2LQ2wh , you can type (R^2*L)/(Q^2*w*h) ) b) Using the provided data: cross-section width w = 20 mm, cross-section hight h = 93 mm, length of the beam L =3 m , beam material’s Young’s modulus Q =226 GPa, applied bending moment MB = 11 kN.m The value of the deflection at Point B caused by MB ( Part I) can be calculated as ......(in mm)Laplace transformation
- Electric drives have a wide range of applications in various industries. One common application is in the manufacturing industry, where electric drives are used to control the speed and torque of electric motors that drive various machines and equipment. For example, electric drives are used in conveyor systems, pumps, fans, compressors, and machine tools to regulate the motion and force required for different manufacturing processes. 1. Create simple Process Flow Diagram (PFD) of electric motor used in pumps.Chapter 7, Problem 63, there is an 'h' value that is solved when expressing half the width of the Rankine Oval that I am not quite understanding the process by which the value is solved for. Could you break down the process by which h=0.02423 m? It's been a while since I was last in school, so the mathematical method by which 'h' was solved is a little unclear to me.Refer to the Worksheet shown, set up to calculate the displacement of a spring. Hooke's law states that the force (F, in newtons) applied to a spring is equal to the stiffness of the spring (k, in newtons per meter) times the displacement {x, in meters): F= kx. ;Chapter 10, Problem 161CA, Refer to the Worksheet shown, set up to calculate the displacement of a spring. Hooke's law states Cell A3 contains a data validation list of springs. The stiffness (cell 83) and maximum displacement (cell C3) values are found using a VLOOKUP function linked to the table shown at the right side of the worksheet. These data are then used to determine the displacement of the spring at various mass values. A warning is issued if the displacement determined is greater than the maximum displacement for the spring. Use this information to determine the answers to the following questions. Write the expression, in Excel notation, that you would type into cell 86 to determine the displacement of the spring.…
