The width of a tenpin bowling pin, at it's widest point, is 4.5 inches. This is where the bowling ball actually contacts the pin.
it depends on the type of the pin
about 1mm yes
The head or the point of the pin? I would measure the head in millimeters and the point of the pin in micrometers.
none of the above
The messenger pin is a pin that goes across the width of the deck and takes out another pin. This is usually in reference to the 7 taking out the 10 or vice versa. Other names for the Messenger include: birddog, scout, shrapnel, or rogue pin.
The width of a bowling lane is 39 inches (41 in very rare occurances) and from foul line to head pin, it is 60 feet long.
The pin deck is the same width as the lane itself, consisting of 39 boards. The head pin is situated on the 20th board, with all other pins 1 foot away from each other.
Assuming a straight shot:width of the ball + width of the pin + width of the ball:8.59" + 4.77" + 8.59" = 21.95"In reality making a 10 pin (edge of the lane) or making a 5 pin (middle of the lane) have the exact same window to be converted. The problem comes for bowlers who hook the ball and may stray to the right of the window hoping to hook back but instead ending up in the gutter. The moral of the story is to throw a straight ball at all single pin spares for the most consistent chance of make these.
A 4-pin fan header is a PWM (pulse-width modulation) fan header. As opposed to a traditional 3-pin, a 4-pin is more sophisticated in the way it controls fan speed. The 3-pin fans use DC (power) control. Unfortunately if you have a fan that has LED lighting with a 3-pin header the lights will dim with along with the decrease in fan speed, and vice versa. The fourth pin allows digital (PWM) control without having to power down or power up the entire fan itself.
