Ahelical gear has 30 teeth and a pitch diameter of 280 mm. gear module is 8 and pressure angle normal to tooth is 20°. the force normal to the tooth surface is 4500 n. determine the kw transmitted at 620 rpm.

In physics the desire of an object to keep doing what it is doing is termed?

A10 kg box initially at rest is pulled 18 meters across a horizontal, frictionless surface by a 40 n force. what is the block’s final velocity over the 18 meters?

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.6 m below the tank bottom which is a = 6.7 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute). report your answer in meters to two decimal places.
