What is the function of shear keys in the design of retaining walls?

In determining the external stability of retaining walls, failure modes like bearing failure, sliding and overturning are normally considered in design. In considering the criterion of sliding, the sliding resistance of retaining walls is derived from the base friction between the wall base and the foundation soils. To increase the sliding resistance of retaining walls, other than providing a large self-weight or a large retained soil mass, shear keys are to be installed at the wall base. The principle of shear keys is as follows: The main purpose of installation…

Different Types Keys and Cotters With Images

A machine runs by the power supplied to it by a prime mover such as, motor, engine, etc. The power is transmitted from the prime mover to the machine through a coupler which couples the shafts of the prime mover and the machine. The most commonly employed method to connect a shaft and a part is to drive a small piece of metal, known as key between the shaft and the hole made in the part mounted over it. The key will be driven such that it sits partly into…

Comparison Between Keys and Cotters

The main difference between keys and cotters are as follows: (a) Keys are driven parallel to the axis whereas cotters are driven perpendicular to the axis. (b) Keys are used in parts subjected to torque whereas cotters are used in parts subjected to tensile or compressive force. (c) Keys resist shear over a longitudinal section whereas cotters resist shear over two transverse sections. Cotter Joints Cotter joints are used to connect together two rods rigidly to transmit power in the length-wise direction. Sometimes when it is required to increase the…

What Is Hashing Algorithm?

Machine software engineers have been utilizing hashing capacities for quite a long time. These capacities are regularly utilized as a part of the zones of security, information access, or information acceptance. A hashing calculation is a scientific capacity that changes over a variable-length series of characters into an altered numerical worth. There are numerous sorts of calculations accessible today. Each one sort is intended for a particular reason. A hash capacity is a numerical capacity that makes a hash esteem from a set of character strings. At the point when…
