Question 1Look at the imageon the left of thegears of a winebottle opener.What type of gearsystem is this?Is this simplemachine a forcemultiplier orspeed multiplier?How does thismachine make iteasy to uncorkthe wine bottle?Question 3Look at the eggbeater.Will this type of gearingproduce speed or forcemultiplication. Explain.Question 2 Question 4Determine the MA for Gear train AB.A force of 5 N is transmitted.Determine the MA for Gear train ABC. A forceof 12 N is transmitted.44
Reducing speed and increasing torqueWorm gearThe worm is always the driver.The worm gear gives the highest decrease in speedand the highest increase in torque. This is becausethe number of teeth for the worm is one.If the wheel of a worm gear system has 36 teeth, what will thegear ratio, velocity ratio, and mechanical advantage be?The gear ratio will then be:45
