National Defense purposes. Before the US entered WWII massive support was being transferred to Russia for its defense against Nazi Germany. Bases to support this effort had to be built in Alaska and the entire road network was built by Army Engineeers.

To calculate the weight of a given amount of steel in the metric system you simply multiply the volume of steel in cubic meters times the SG of steel (typically 7.85 but it varies slightly depending on the type of steel). The answer will be in metric tonnes or MT.

Technical drawings must be done with accuracy and must be easy to be understood. This can be done through manual sketching, through an instrument or even with the use of computer-aided drawing systems.

In Pakistan civil, mechanical and electrical engineering are on top. field of computer sciences is also good i.e software engineering is very best in pakistan but all over the world provided that you are good at programming because now a days it is very difficult to meet a programmer in the market and those who are good software developers they are earing more than one lackh and in the coming four years software engieering will be on the most top and the will be needed because it is the era of information technology

Reinforcement enhances learning by encouraging desired behaviors through positive rewards or the removal of negative stimuli. It increases motivation and engagement, leading to improved performance and retention of information. Additionally, reinforcement helps in building confidence and promoting a positive learning environment, as individuals feel more supported and recognized for their efforts. Overall, it fosters a proactive approach to skill development and behavior modification.

A bedding plane is the area of separation between rock strata made by a cyclical or situational deposition of sediment. Bedding planes are originally parallel to the horizon, but the strata inclination can be altered by crust moving events.

Dams have been called as multipurpose projects because the water it stores is used for many things apart for irrigation. For example: 1. It can be used for domestic purposes 2.Electricity generation 3. Industrial uses, etc.

The Eiffel tower was built as the symbol for Exposition Universelle of 1889, a World Fair marking the 100th anniversary of the storming of Bastille, the beginning of the famous French Revolution. In a twisted, yet upright way, it stands for France's freedom from Tyranny!

It decorates the west side of Paris quite nicely and attracts zillions of tourists. I believe there are broadcasting antennae on top as well. It's also a great place to see the rest of the city. Bit crowded though.

It is a monolythic concrete beam consisting of a web and a flange to form the shape of a"T" .

Arch bridges are in the shape of an upside down "U" with mainly steel beans, while supension bridges have one or two Major verticle beams with strong wire connecting to the bridge.

Before crops were harvested by machines, many, especially cereals, were cut by hand using a scythe. After cutting, they were gathered into bunches - a good armful at a time, and tied - those bunches are sheaves. They were then stacked in small piles, usually called stooks, and left to dry completely before piling into very large stacks, called either stacks or ricks. During the winter, the wheat, oats, barley or whatever, was thrashed from the straw.

35N/mm2

the above answer is terrible. at 14 days there is no guarantee of what the strength will be, as strength gain is rapid with pue OP it will tend t be greater than 50% of the target characteristic strength; however, with any pozzolans in the mix (e.g. PFA/GGBA) the strength gain over time is slower and can be espected to achieve greater strengths than that of pure OPC

the question is too vague to answer. the mix design is pivotal in calculating strength

Engineers will consider the forces involved on the concrete slab and come up with a figure of -ve and +ve rebar needed to resist the moments. They will also consider the strength of concrete required, 20mpa, 32 mpa etc. Sometimes temperature steel is also added.

They will usually come up with a figure like 575mm/m2 of rebar needed in the +ve and another figure for the -ve. Then the designer steps in, looks up their rebar tables and works out that to cover 575mm/m2 they can use 4-N20-LL-320 or something. Which stands for 4 size n20 (20 dia) bars, LL shape, so a 90 bend on both ends, at 320 spacing.

1800 pounds per square inch = 124.106 bar.

For sidewalk code is generally every 30 ft. For a masonry wall it is also every 30 ft. Place celotex every 30 feet on a sidewalk and this will eliminate buckling of the slab.

A GED by itself is not enough to enter any field of engineering today. Use the GED to get admission to an engineering college and work toward a degree. A masters is preferable, but some places will hire engineers with a bachelors and then provide educational assistance to get the masters while working for them.

Evading is a strip (generally wooden) that covers the lower part of an inside wall. Its motivation is to cover the joint between the wall surface and the floor. The fundamental capability of an evading board is to shield walls from harm.

The term "point of contraflexure" is often used in structural engineering, specifically in the context of analyzing and designing beams subjected to bending loads. In simple terms, the point of contraflexure is the location along the length of a beam where the bending moment is zero.

When a beam is subjected to bending loads, it experiences tensile (positive) bending moments and compressive (negative) bending moments along its length. The bending moment varies along the beam, reaching a maximum at the points where the bending is the most significant. These points are usually located near the supports of the beam.

However, in some cases, particularly in continuous beams or beams with complex loading conditions, there may be a section along the beam where the bending moment changes direction from positive to negative or vice versa. This section is known as the point of contraflexure.

At the point of contraflexure, the bending moment is zero, and the beam's curvature changes direction. This point is essential in the analysis and design of structures as it affects the internal forces and stresses within the beam.

Identifying the point of contraflexure is crucial for engineers to ensure the beam's stability and design it appropriately to handle the bending loads effectively. The bending moment diagram is used to visualize the variation of bending moments along the length of the beam and to locate the point of contraflexure if it exists.
