Abstract

Four pieces of apparatus, a mounting for a gyroscope, a Newton's second law of motion demonstration, a short wave oscillator and a stroboscope for measuring phase change in A. C. circuits are described. For the latter two the actual apparatus is shown. Each piece is an effective teaching device and can be made for a small fraction of the cost of purchasing similar equipment from the manufacturers. The ideas for these pieces of apparatus have been picked up in various places and no special claim for originality is made.
