wooden block and the wooden surface of a horizontal and inclined plane will be derived and measured. By graphing these data, coecients of static and kinetic friction will be obtained. As you perform this experiment, theoretical quanti-ties will be determined prior to measuring for Part 2 through Part 5. These calculations will require the free-body diagram solution method (refer to Page 28 A basic modern optical theodolite typically consists of a small telescope which is connected to two angle measuring mechanisms, one for measuring horizontal angles and one for measuring vertical angles. It sits atop a rotatable base with a leveling mechanism on a tripod. Once the theodolite is set up, the telescope is turned to spot the desired point and then the angle from the point that the
