On Page 3 of the worksheet, the Volume of each cylinder (Vcyl) function does not take into account the additional volume created by the caved spherical cap profile of the piston head or the engine block.
The Volume of engine block (Veb(heb)) function has already been defined. The task is to define the Volume of piston head (Vph(hph)) function in the provided space.
1. Click in the area next to Volume of piston head.
2. Type V.
3. On the Math tab, in the Style group, click Subscript. Type ph.
4. Type (h.
5. On the Math tab, in the Style group, click Subscript. Type ph.
6. From the Operators and Symbols group, click the arrow next to Operators, and select Definition from the Definition and Evaluation area.
7. From the Operators and Symbols group, click the arrow next to Constants, and from the Math area, select Pi.
8. Type / 6 and press RIGHT ARROW on your keyboard once, to get the blue pointer in the position shown.
9. Select Operators, from the Operators and Symbols group, and in the Algebra area, select Multiplication.
10. Type h, click Subscript from the Style group and type ph.
11. Select Operators from the Operators and Symbols group, and in the Algebra area, select Exponentiation and type 2. Press RIGHT ARROW on your keyboard once to move the blue pointer out of the exponent.
12. Click the arrow next to Operators from the Operators and Symbols group, and in the Algebra area, select Multiplication.
13. Type (3.
14. Click the arrow next to Operators from the Operators and Symbols group, and in the Algebra area, select Multiplication.
15. Type d, click Subscript from the Style group, and type phcap.
16. Press SPACEBAR once to select dphcap, and then press the SPACEBAR a second time to select both the 3 and the dphcap. Type / 2.
17. Press RIGHT ARROW once to move the blue pointer out from the denominator and type –h. Click Subscript from the Style group and type ph. . The volume of piston head equation should look as follows:
