Question

To better understand the concept of static equilibrium a laboratory procedure asks the student to make a calculation before performing the experiment. The apparatus consists of a round level table in the center of which is a massless ring held in place with a pin. There are three strings tied to different spots on the ring. Each string passes parallel over the table and is individually strung over a frictionless pulley (there are three pulleys) where a mass is hung. The table is degree marked to indicate the position of each string. There is a mass of m1 = 154 g located at ?1 = 26.2

Explanation / Answer

tensions in strings be T1 and T2 and T3 T1 = 1.51 N ,,T2=2.156 N T3 = ? consider effects of T1 and T2 vertical component forces = 0.667 -2.15 = - 1.48 j horizontal component forcess = 1.35 + 0.18 = 1.54 i T3 = -1.54 i+ 1.48 j magnitude of T3 = 2.13 N m3 = 0.217 Kg = 21.7 grams direction = 133.86 degrees
