- (a) Find the ratio of the pulley diameters. ____________________
- (b) Automotive Trades A small gasoline engine has a maximum cylinder volume of 520 cu cm and a compressed volume of 60 cu cm. Find the compression ratio. ____________________
(a)
The ratio of the diameters of the pulley.
Answer to Problem 1P
The ratio of the diameters of the pulley is
Explanation of Solution
Given that the diameter of the one circle is 10 inch and the diameter of another circle is 4 inch.
Find the ratio of the diameters of the pulley as follows.
Thus, the ratio of the diameters of the pulley is
(b)
The ratio between the maximum cylinder volume and the compressed volume of the engine.
Answer to Problem 1P
The ratio between the maximum cylinder volume and the compressed volume of the engine is
Explanation of Solution
Given that the maximum cylinder volume is 520 cu cm and the compressed volume is 60 cu cm.
Find the compression ratio of the engine as follows.
Thus, the ratio between the maximum cylinder volume and the compressed volume of the engine is

- Express these ratios in lowest fractional form. 11. The cost and selling price of merchandise are listed in the following table. Determine the cost-to-selling price ratio and the cost-to-profit ratio. NoteProfit-selling price-cost.arrow_forwardSpeed of Sound in the North Atlantic The speed of sound in ocean water is 1148.94meterspersecond, provided that the ocean water has a salinity of 35 35partsperthousand, the temperature it 0degreesCelsius, and the measurement is taken at the surface. If any one of these three factors varies, the speed of sound also changes. Different oceans often differ in salinity. In the North Atlantic Central Water the main body of water for the northern half of the Atlantic Ocean, the salinity can be determined from the temperature, so the speed of sound depends only on temperature and depth. A simplified polynomial formula for velocity in this body of water is V=1447.733+4.7713T0.05435T2+0.0002374T3+0.0163D+1.675107D27.1391013TD3 Here V is the speed of sound in meters per second, T is the water temperature in degrees Celsius, and D is depth in meters. This formula is valid for depths up to 8000 meters and for temperatures between 0 and 30 degrees Celsius. a. What type of polynomial is V as a function of T alone? Of D alone? b. For a fixed depth of 1000meters, write the formula for V in terms of T alone. c. Graph V as a function of T for the fixed depth of 1000meters. d. What is the concavity of the graph from part c? What does this imply about the speed of sound at that depth as temperature increases?arrow_forwardIt is sometimes impractical to make engineering drawings full size. If the part to be drawn is very large or small a scale drawing is generally made. The scale, which is shown on drawing, compares the lengths of the lines on the drawing to the dimensions on the part. A scale on a drawing that states 14=1means the drawing is one-quarter the size of the part. It is expressed as a ratio of 1:4 or 14 . A scale drawing that states 2=1means that drawing is double the size of the part. It is expressed as a ratio of 2:1 or 21 . The actual dimensions of a steel support are given in Figure 20-11. All dimensions are in inches. Using the proportion given, compute the lengths for each unknown in the table. Round the answers to 3 decimal places where necessary.
