Advantages and Disadvantages of Different Types of Gears Spur Gear They offer constant velocity ratio Spur gears are highly reliable Spur gears are simplest, hence easiest to design and manufacture A spur gear is more efficient if you compare it with helical gear of same size Spur gear teeth are parallel to its axis. Hence, spur gear train does not produce axial thrust. So the gear shafts can be mounted easily using ball bearings. They can be used to transmit large amount of power of the order of 50, kW Disadvantages Spur gear are slow-speed gears Gear teeth experience a large amount of stress They cannot transfer power between non-parallel shafts They cannot be used for long distance power transmission.

Typical bridge designs include beam, truss, girder, suspension, arch, cable and cantilever. Forces that come into play in bridge design and engineering include compression, tension or stretch, deck flexibility, torsion or twisting and shear, the force that stresses the bridge materials laterally across the bridge deck.

One of the oldest arch bridges still in use today, a testament to its Roman engineering, includes the Ponte dei Quattro Capi bridge which dates back to 62 B.

Beam, Truss and Girder Bridges The beam, truss and girder bridges work simply, much like laying a plank between two banks. Piers or posts on either end support a flat bridge deck that spans the gap between the posts. The bridge deck consists of beams, like hollow box girders, an open frame or truss that spans the posts or supports on either end.

The bridge deck must withstand compression above and tension from below. Most of the covered bridges found in New England, represent these types of bridges made from wood. Economical because of the abundance of wood, beam bridges are not as strong as steel and require constant maintenance.

One of the oldest engineered bridges, the arch bridge, supports a deck built above two abutments that serve as the curved arch. Made from masonry and stone, the arch design prevents any one area of the bridge receiving too much tension.

Beam, Truss and Girder Bridges

With abundant building materials, arch bridges are durable and strong, requiring little to no maintenance. Sciencing Video Vault Suspension Bridges The first suspension bridges date back to the 15th century and typically span waterways, because the bridge deck requires little to no access from below to build.

Tall pillars support this bridge, evenly spaced across the span as needed, from which massive wires on either side sweep from pillar to pillar. From these sweeping wires suspenders hang vertically to hold up the bridge deck. The tension in the cables and the compression from the pillars work together to cancel out the force of gravity, making them strong and efficient.

These bridges can span great distances once the pillars are in place, but they are costlier to build, require extensive upkeep and the bridge decks can move and twist when exposed to fierce winds. Cantilever Bridges Cantilever bridges offer a way to build a continuous bridge across multiple supports to effectively distribute the load evenly.

A portion of the bridge provides an anchor that supports a bridge deck that extends to either side of the support that requires precise counterbalance engineering.

The advantage of building this bridge design comes during the construction phase. But cantilever bridge designs do require precise engineering because the counterbalance weights can affect their strength if incorrect, especially if contractors build the segments slightly differently.For the rest of this lesson, we will explore each type of business organization and explain the advantages and disadvantages of each.

Advantages & Disadvantages of Different Types of Communication by Kimberlee Leonard - Updated June 28, Communication is defined by many different terms, with four types commonly found in business environments. Straight stairs are certainly one of the most common types of stairs found in both residential and commercial properties.

Advantages of straight Stairs: Straight stairs tend to be the easiest to go up and down or ascend/descend as we say in the industry.
