      For a lever, the DE is the distance from the fulcrum to the effort. The DR is the distance from the fulcrum to the object being moved. While using a lever, the effort force is exerted through a distance of 45 cm while the resistance moves 5 cm. An effort force of 20 N was used. 15. What is the mechanical advantage of the machine? 16.

      The active element of a certain laser is made of a glass rod 30.0 cm long and 1.50 cm in diameter. Assume the average coefficient of linear expansion of the glass is equal to 9.00 ( 10–6 (°C)–1. If the temperature of the rod increases by 65.0°C, what is the increase in (a) its length, (b) its diameter, and (c) its volume?
