Choosing a Durable Turntable

Turntables are popular nowadays because of the rave and hiphop culture. Usually, disc jockeys use turntables to mix with the songs to have a signature sound.

Turntables are rotating platforms that refer to either music or technology devices. In the music scene, a turntable is a type of gramophone or phonograph driven by a motor at a constant speed. They are also referred to as a musical instrument of the modern era used in “turntablism.” Turntablism is the art of playing the turntables.

There are also other references in the music scene such as the song from a popular girl group from the nineties called TLC and the so-called “turntable hit,” a hit vinyl single commonly triumphant in the airplay tables than in sales.

In terms of technology, the word turntable is the rail, motor vehicle, display, Lazy Susan, and a pottery wheel. A turntable rail is a device for railroad facilities in order to turn rolling stocks or automotives onto or around the radial arranged tracks. This type is also called a “rotary transfer table.” The motor is a manual or motorized device installed in a garage floor or a driveway. This device rotates motor vehicles to facilitate a safer or an easier outlet of the vehicle.

Those used for display are usually motorized tables solely for displaying various kinds of items. A pottery wheel or a potter’s wheel is also called a turntable for it uses a rotating table to shape the spinning clay. Lazy Susans are also a form of turntable placed at the top of tables so that items particularly food is easily reached even if the person is at a sitting position.

Selecting a Turntable (Musical Instrument)

A lot of people believe that traditional vinyl records give a richer and warmer sound for music. Numerous disc jockeys or DJs are experts in playing turntables for it allows them easy control and operation so as to what music is played. Although our technology is somehow out of date, you can still see turntables in various places.

You must first take note on the kinds and number of outputs you want or need to have in your turntable. There are some recently manufactured that come with USB connectors. This makes transferring of music from LP to the computer as easy as snapping your fingers. Make sure that the product you are going to buy properly connects with your mixing board, computer, and speakers.

Turntables not vibrating too much are more preferable. Look for those that appear to be durable. If possible, ask for warranties. Those made of plastic are not advisable for they are not durable. It also tends to vibrate more. Vibrations may disrupt the sound and adversely affect the audio quality.

Bend over to the belt-drive type of turntables meaning the motor inside that turns a belt and makes records spin. Direct-drives spin records automatically though they also disrupt the music because of vibrations. On the other hand, belt-drive turntables reduce the vibrations thus giving you a clearer sound. If you are into DJ scratching, select the direct-drive type to allow better control.

Make sure that your turntable has a Very Good seclusion from the stylus. Check this by playing a vinyl record and slightly tapping the turntable’s base. Thumps or clicks indicate that it is made of less solid construction and therefore less durable also.

Sometimes it is also advisable to look for a certain brand trusted to produce quality products. You could gather reviews from different media and personal testimonials from current users to get an idea.

What is the magnitude of the vertical portion of the contact force on the shaker of the turntable?

Joey likes to play naughty with their lazy Susan family (this drives Mom crazy because it is old). He puts the salt shaker near the edge and tries to spin the tray at a speed so that the shaker just turns without slipping. Joey believes that the shaker just stays at the plate when you're making a complete revolution every two seconds. Joey's older sister measures the mass Shaker to 89 grams. It also measures the radius of the plate at 0.21 m, and she is able to calculate the speed of the shaker as it successfully moves in a circle is 0.6594 m / s. What is the magnitude of the vertical portion of the contact force on the shaker of the turntable? Thanks

Trick question (or this is just a Part A of a multi-part problem). Despite all the strange things about spinning (meaning that the horizontal forces), this is only a matter of a salt shaker on a table. Force of gravity = mg (below) the normal force of the rotating platform shaker = mg (up). You get m. You know g. Plugnchug. Simple as that.
