fuse
Yes
girder isa a large strong piece of metal or wood.
to be able to create a right angle on a piece of metal
In a computer system, the motherboard holds all the other circuit boards. The video, sound, game ports, and all other daughter boards are attached to this important piece of hardware.
Grain flow is a typical grain pattern generated during forging of metal. When a piece of metal is cold or hot forged by applying external force or pressure, then metal starts deforming normal to the direction of application of pressure. During the process of permanent deformation, metal grains get deformed & generate what is known as" flow lines ". This is called Grain Flow. It can be seen by chemically etching cross sectional piece of forge metal shown fig below.
A circuit breaker is designed so that it will trip when the electric current is too high. That is the purpose of a circuit breaker. If there is a metal piece on the circuit breaker that prevents it from tripping, it is useless. Perhaps someone has altered it.
It is called a door closer. The door closer controls the speed at which the door closes to prevent it from slamming shut.
These jacks are used in audio systems to patch in a piece of outboard gear. When you plug in the cable, the circuit is interrupted and sent to the external gear. When you remove the cable, the circuit 'closes' and sends the signal on through. A headphone jack is a closed-circuit jack. When you plug in your headphones, the circuit to the internal speaker 'opens' and sound is sent only to the headphones. When you unplug them, the circuit to the speaker 'closes' and you hear sound through the speaker again.
A thermostat contains a small piece of metal called a bimetallic strip that bends when it gets hot, allowing it to regulate temperature by opening or closing a circuit.
A fuse is an electrical safety device that contains a piece of metal that melts when the current flowing through it becomes too strong. This melting of the metal breaks the circuit and prevents overheating of the electrical system.
electricity Or... more accurately... electromagnetism. The action of "tapping" on a sending unit of a telegraph system closes an electrical circuit that sends DC power to a coil with an iron core. The electricity running through the coil causes it to be magnetized, which draws a spring-loaded piece of metal against the core causing it to click.
A circuit is just as long as a piece of string.
A sharp metal piece is typically called a "metal shard" or a "metal splinter."
A 'metal filing ' is a tiny piece of metal that is rubbed off from a large piece by a file.
Integrated Circuit
An Integrated Circuit (IC)
In a torch (flashlight), the current passes from the positive terminal, through the bulb, and returns back in the negative terminals, making a complete circuit. When the switch is moved to the on position, a metal piece inside the case touches the positive terminals of the battery, the circuit is completed, and the torch turns on. Move the switch to the off position, the metal piece no longer touches the positive terminals of the battery, and the torch turns off.
