Physics: Compression of column; constant of a spring, 1. A 4.8-m-tall, 30-cm-diameter concrete column supports a 5.0Ã?105 kg load. By how much is the column compressed?
The electric field has been measured to be horizontal and to the right everywhere on the closed box. All over the left side of the box E1 = 120 V/m, and all over the right, slanting, side of the box E2 = 250 V/m. On the top the average field is E3..
