Figure 4.
Beam with Rider
o. You interpret the beam information in Figure 4 by noting the location of
the rider on the beam and considering the weight of the rider. If you move a 10-mg
rider from zero (at the center) to 10 at the right side of the beam, it has the
same effect as-placing a 10-mg weight on the right pan in Figure 3.
Leave the
riders on the beam to prevent a change in the center of gravity of the moving
system. This change is often caused by the removal and replacement of riders.
p. Our description of the transposition method of weight measurement needs
clarification. Your first step is the determination of the unknown by the direct
weighing method. Next, you transpose the loads (move the unknown and standard to
opposite pans) so that the unknown weight (mass) is on the left pan.
After a
second reading is taken, determine the true
