What is the mechanical advantage if the radius of the wheel is 49 cm and the radius of the axle is 7 cm? MA = Radius of Wheel / Radius of the Axle a 21 b 3 c 7 d 16
The mechanical advantage (MA) is equal to the radius of the wheel divided by the radius of the axle.
In this case, the radius of the wheel is 49 cm and the radius of the axle is 7 cm.
Therefore, the mechanical advantage (MA) is:
MA = 49 cm / 7 cm = 7
So the mechanical advantage is 7.
The correct option is c) 7.
