*Problems will be
graded only if they are written neatly.*

*No late homework!
There will be no extension for the due date.*

*Show all working (no
grade will be given if you write just the final answer for a problem).*

**1-** A foreign manufacturer lists the fuel
consumption for a new automobile as 15 kilometers per liter (km/L). Determine
the fuel consumption in miles per gallon.

**2-** The value of G (universal gravitational
constant) used for engineering computation in the ^{-8})
ft^{3}/(slug.s^{2}). Use the
conversion factors to determine a value of G with units of m^{3}/(kg.s^{2}) suitable for computation in the SI
system of units.

**3 & 4-** Solve problems, **2-2 and 2-3** of Hibbler’s book.

**5-** Solve **problem
2-1** of Hibbeler’s book.

Steps:

· Find all the unknown angles in the figure.

·
Find the resultant of F_{2} and F_{3}
and also the angle this resultant (say R_{1}) makes with the horizontal
line.

·
Find the angle between R_{1} and F_{1}.

·
Find the resultant of R_{1} and F_{1}.

Remember that you can use any of parallelogram or triangle laws that we discussed in class.

Alternatively, you can find the resultant of F_{1}
and F_{2} and name it R_{1} and then find the resultant of R_{1}
and F_{3}. This is a good way to check the answer you found using the
steps mentioned above.
