Answer:

Please find attached the diagram end result of the truss with the member reaction forces labelled with the amount of forces as required, created with Microsoft Visio

Explanation:

To answer the question, we note that the sum of the forces in the Truss is zero

Therefore, we have, ∑Fₓ = [tex]\Sigma F_y[/tex] = 0 N

The forces on the members CD and AD are therefore as follows;

Horizontal forces;

[tex]F_{CD}[/tex] × cos(45°) - [tex]F_{AD}[/tex] × cos(30.964°) = 100.0 N...(1)

[tex]F_{CD}[/tex] × sin(45°) + [tex]F_{AD}[/tex] × sin(30.964°) = 750.0 N...(2)

Solving the above system of equations using a graphing calculator gives;

[tex]F_{CD}[/tex] ≈ 715.94 N (Tension)

[tex]F_{AD}[/tex] ≈ 473.76 N (Compression)

[tex]F_{Cy}[/tex] + [tex]F_{Ay}[/tex]  = 750.0 N

[tex]F_{Ax}[/tex] = 100.0 N

From ∑M[tex]_c[/tex] = 0, we have;

[tex]F_{Ay}[/tex] × 8 = 750 × 3 + 100 × 3

[tex]F_{Ay}[/tex] = 2550/8 = 318.75 N

∴ [tex]F_{Cy}[/tex]  = 750.0 N - [tex]F_{Ay}[/tex] = 750.0 N - 318.75 N = 431.25 N  

Answer:

Specialized Bicycle Components, Inc., colloquially known as and stylized as SPECIALIZED, is an American company that designs, manufactures and markets bicycles, bicycle components and related products under the brand name "Specialized", as well as the premium and professional oriented "S-works".

The Morgan Hill, California-based company was founded in 1974 by Mike Sinyard.

The company was founded in 1974 by Mike Sinyard, a cycling enthusiast who sold his Volkswagen Bus for $1,500 to fund a cycle tour of Europe, where he bought handlebars and stems made by Cinelli to take back to the US. Sinyard started out importing Italian bike components that were difficult to find in the United States, but the company began to produce its own bike parts by 1976, starting with the Specialized Touring Tire. In 1981, the company introduced its first two bikes, the Sequoia, a sport-touring design and the Allez, a road bike. Specialized also introduced the first major production mountain bike in the world, the Stumpjumper, in 1981. Like the Sequoia and Allez, the Stumpjumper was designed by Tim Neenan and based on an early Tom Ritchey design. Specialized continues to produce bikes under the Stumpjumper name, including both hardtail and full-suspension models. An original Stumpjumper is displayed in the Smithsonian Institution in Washington, D.C. In 1989, Specialized introduced the Epic, the world's second mass-production carbon fibre mountain bike.

Answer:

Normally closed (NC)

Explanation:

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

[tex] V = IR[/tex]

Where;

V represents voltage measured in voltage.

I represents current measured in amperes.

R represents resistance measured in ohms.

A switch can be defined as an electronic component or device that is typically used to prevent or allow the flow of electric current (electrons) from one point to another in an electrical circuit.

There are two logical forms used for designing a switch and these includes;

I. Normally opened (NO).

II. Normally closed (NC).

A Normally closed (NC) contact allows current to flow when the switch's operator is not activated.

Basically, a Normally closed (NC) contact would always remained closed unless a certain (specific) condition is met. Thus, when the contacts are moved, the circuit becomes open and thus, prevents the flow of electric current in the circuit.

Single Pole Single Throw Switch

Single Pole Double Throw Switch

Double Pole Single Throw Switch

Double Pole Double Throw Switch

Push Button Switch.

Toggle Switch.

Limit Switch.

Float Switches.

In the simplest case, a switch has two conductive pieces, often metal, called contacts, connected to an external circuit, that touch to complete (make) the circuit, and separate to open (break) the circuit

Two basic categories of electrical switches are manual and automatic.

A switch that opens and closes an electric circuit is typically electromechanical in nature. This, correspondingly, stops and starts the flow of electric current.

A mechanical handle, lever, or rocking mechanism is used to manually activate (or push up or down) a toggle switch. These are frequently employed as switches for lighting.

An electrically controlled switch is a relay. It is made up of a set of working contact terminals and a set of input terminals for one or more control signals. Any number of connections in different contact configurations, such as making contacts, breaking contacts, or combinations of both, may be included on the switch.

Therefore, electrical switches can be divided into two fundamental categories: manual and automatic.
