are compared to the theoretically calculatedvalues. This activity is designed to strengthen students’ knowledge through practical applicationof concepts studied during the first quarter of Statics, such as position, unit vectors, free bodydiagrams, and equilibrium of particles.The schematic in Figure 2(b) depicts a 3D rendering of the sample problem with dimensions.The students are tasked with determining a unit vector along the line of action of one of thecords. The potential solutions are chosen such that the answer can be surmised based on somebasic concepts: (1) unit vectors are of a unit length (i.e. u x2 + u y2 + u z2 = 1 ), (2) the positiveorientation of axes changes the sign of vector components, and (3) cords apply force in tension

This is then attached to the drive, and outputs to a low-powerLED light. The instructor uses different attachments to mimic a waterwheel, a wind turbine, and steampower and demonstrates that a turning motion generates the electricity necessary to light the LED. Themouse-wheel can also be powered with a small hand crank or a running rodent (note consistent powergeneration requires constant quick rotation).Through this activity, students learn how different energies, renewable and nonrenewable, areimplemented.
