“Once you pull the trigger, it will keep firing as long as the trigger is pulled down, until there are no more bullets,” McDevitt says. Unlike a semi-automatic weapon, an automatic weapon-an example would be a machine gun-continues firing without the shooter having to pull the trigger again. While we may associate the term “semi-automatic” with rifles, which are long guns with grooves in the barrel that help improve accuracy, it can apply to any type of weapon, including handguns. Illustration by Hannah Moore/Northeastern UniversityĪ semi-automatic weapon is any weapon where the shooter pulls the trigger, one bullet is fired and a new bullet is automatically loaded. What are the terms used in the bill to describe firearms? Automatic rifle vs. What do these restrictions mean, and how effective would they be if passed? Here’s a primer on key gun terms, from Jack McDevitt, professor of the practice in criminology and criminal justice at Northeastern. Phil Murphy called for laws that make gun manufacturers vulnerable to civil lawsuits, and California lawmakers pushed for stricter gun control. Last week, New York passed a bill raising the age to buy a semi-automatic rifle to 21 and expanding red flag laws, CNN also reports. The federal legislation follows a push for gun control at the state level. The changes are unlikely to make it past a Senate vote. The House bill is wide reaching: It would raise the minimum age to buy some semi-automatic weapons to 21, strengthen bump stock and “ghost gun” regulations, ban high-capacity magazines, and give local governments power to start high-capacity magazine buyback programs, CNN reports. Popular examples of gearboxes in current new cars which offer automatic and semi-automatic functionality include the Volkswagen Group’s DSG, Ford PowerShift and BMW DCT.įind prices for new cars at .The House passed the Protecting Our Kids Act on Wednesday, hours after hearing harrowing testimony from gun violence survivors and their families, and two weeks after a shooter killed 19 children and two teachers at Robb Elementary School in Uvalde, Texas. While there is less effort and engagement involved than with a manual gearbox, driving a car semi-automatically still gives the driver the pleasure of pushing the car through the gear ratios using a gear-selecting-lever. A gearbox that can be used semi-automatically and includes these paddles is known to some by the informal term ‘flappy-paddle gearbox’. With no clutch pedal or large gearstick necessary, someone who drives a car semi-automatically will use either a small gear lever with simple up or downshift changes or use paddles mounted on the outside edges of the steering wheel. Because of this, a semi-automatic function can prove more appealing to drivers. However, some gearboxes that change gears electronically can struggle completing this function as quickly and as smoothly as drivers would want when the car makes a sudden change of speed following, say, heavy braking. Since electronic equipment takes care of the clutch, the gearbox can time its gear changes to the torque of the engine and make each gear change fast, precise and smooth. The key difference is that while a manual ‘box requires the use of a clutch pedal, a semi-automatic removes this part from the driver’s reach and completes its function electronically. Semi-automatic gear changes explainedĪ gearbox that works semi-automatically (also known as automated manual) requires the driver to make gear changes themselves, like with a manual gearbox. But many of the new cars on the market nowadays which offer a dual clutch/automatic gearbox can be operated by the driver in a semi-automatic fashion if they choose. Conventional cars nowadays will come with either a manual or automatic gearbox but there is a variation of the latter known as the semi-automatic gearbox.įinding a car which has a gearbox that only works in a semi-automatic manner is very rare nowadays, thanks to the rise of dual-clutch systems.
