In a gear set that has a ratio of 2:1. Choose All correct answers. There may be more than one.
Torque will double from the input drive gear
Speed of the driven gear will be reduced by half
Toque of the driven gear will be reduced by half
Speed of the driven gear will be double
In a gear set that has a ratio of .5:1. Choose All correct answers. There may be more than one.
Torque will double from the input drive gear
Speed of the driven gear will be reduced by half

On a 4 or 5 speed rear wheel drive (RWD) transmission: Choose all correct answer. There maybe more than one answer.
4th gear is direct drive
4th gear has a gear ratio of 1:1
4th gear has a gear ratio of .8:1.
4th gear drives the counter shaft driven gear.
When calculating the gear ratio on a gear set that incorporates and idler gear.
You must use the two gear ratio math method
You can ignore the idler gear size and calculate using the drive and driven gears only.
You have to measure the size of the gear with a dial caliper before you can calculate the ratio
You must know the speed of the gear first before you can calculate the gear ratio.
