Answer the following statement(s) true (T) or false (F)
1. In a few cases, industrial machines require power at slow speeds and high torque. 2. The gear motor is a speed-reducing motor. 3. A gear motor is larger than a low-speed standard motor of the same horsepower. 4. Gear motors are available in many of the standard motor types, but run only at constant speeds. 5. In gearing, as the output speed is decreased, the torque is increased.

A. at high speeds, non-speed-rated tires distort in the sidewall and tread areas. B. light truck tires run hotter but dissipate heat better than passenger car tires. C. low-profile tires often have one or more sections of sidewall that extend beyond the flange of an expensive aluminum wheel to protect it from damage when it rubs against a curb. D. nylon cap plies are extra plies on the sides of the normal tire plies.
