A V belt of cross section B and width pitch length (Lp) 4430 mm is designated as B4430Lp.

  1. For V belt the standard value of belt angle is 40°.
  2. The groove angle for V belt pulley is from 34° to 38°.
  3. V belts are used for high speeds end.
  4. V belt results in wedging action between the belt and groove, thereby increasing the frictional force and consequently the frictional power.

Below stated are some of the statements about the Alternating current. You need to identify which of the following is incorrect, 1. DC power is far more powerful than AC power. The efficiency and power to size characteristics of DC motors and apparatuses are increased. Lighting by DC (LED) is 75% more efficient than lighting from incandescence. 2. A comparatively high voltage alternating current may be generated and easily raised and dropped by the static equipment known as the transformer, which makes electrical energy transmission and distribution economical, 3. Initial costs and maintenance of the AC motor are less expensive since it has no switch and is less powerful than the DC motor for constant working speed, hence it is desired to create power as alternating current. 4. The great efficiency of transmission in ac makes electric power generation cost-effective, Produced in huge quantities in one station and distributed throughout a vast area.
