A 10 Hp Motor Is Used To Raise A 1000 Newton Weight At A Vertical Distance Of 5 Meters. What Is The Work (2024)

Engineering College

Answers

Answer 1

The work done by a 10 HP motor when it raises a 1000 Newton weight at a vertical distance of 5 meters is 5kJ.

Define work. Explain the rate of doing work.

Work is the energy that is moved to or from an item by applying force along a displacement in physics. For a constant force acting in the same direction as the motion, work is easiest expressed as the product of force magnitude and distance traveled.

Since the force transfers one unit of energy for every unit of work it performs, the rate at which work is done and energy is used are equal.

Solution Explained:

Given,

Weight = 1000N and distance = 5m

A/Q, the work here is done in lifting then

Work = (weight) × (distance moved)

= 1000 X 5

= 5000Nm or 5000J = 5kJ

Therefore, the work done in lifting a 1000 Newton weight at a vertical distance of 5 meters is 5kJ.

wt steel shape is produced by cutting a wide flange beam lengthwise in half. group of answer choices true false

Answers

It is true that wt steel shape is produced by cutting a wide flange beam lengthwise in half.

A beam is a structural component that resists loads mostly applied laterally to its axis (an element designed to carry primarily axial load would be a strut or column). Its primary method of deflection is bending. Reaction forces are produced at the beam's support points as a result of the loads placed on it.

As a result of all the forces operating on the beam, internal stresses, strains, and deflections of the beam are caused by shear forces and bending moments within the beams. Beams differ from one another in terms of how they are supported, their profile (the form of their cross-section), equilibrium circumstances, length, and material.

Assembly is essentially binary code written in a way that people can read it. The assembler then converts the assembly code, line by line, to the corresponding bit code.

What is the difference between Assembly and binary?In essence, assembly is binary code that has been translated into a language that people can read. Then, the assembler takes the assembly code and converts it bit-by-bit to the corresponding bit code.Imagine that there is a table with a line for each potential assembly statement. The statement itself is next on each line, followed by the corresponding bits that the computer can understand on the right.Even so, assemblers also have supplementary features like macros and other features, but the aforementioned functionality is their primary functionality.Binary is just a numbering scheme to programmers. For instance, base2 contains some 0s and 1s. These binary numbers are used by all computers. They interpret the instructions as a list of these numbers. They are not affected by the human-generated code, which is typically produced using a high-level programming language like Python, Java, and others.It is obvious that machine instructions in computers are not really human-readable - most people cannot determine the operational difference between 100010001... and 010001000... by simply looking at a binary or hex representation of the instruction bytes. Simply put, these instructions are machine codes.For instance, in the x86-16 architecture, the following instruction is used as the machine code for loading a value into a register: With a 2-bit addressing mode field and a 3-bit base register, the formula 8B 0E 34 12 denotes mov r16, r/m16, and which register the destination is (in this case, CX). For the avoidance of doubt, the Machine Code is represented using HEX code. Actually, it is simple to translate it to binary, and you have already mentioned that it is "10001011000011100011010000010010. Just like a string of ASCII 0 and 1 but more condensed, HEX is a text serialization format for binary numbers.Such binray/HEX instructions are readable by humans thanks to assembly, which is a higher level programming language than machine code.

Answers

The number of panels that will be required is 1600 panels.

How to calculate the number of panels?

From the information, we have:

Now let each panel generate power = P

Hence, with 2000 panel we have 2000P.

Now, these are 40% efficient so

40% of incident power = 2000P

Incident power = 5000P

Power used by 1 panel = 5000P/2000 = 2.5P

Now we have 50% efficient panel and we have to generate 2000P,

Now 50 % of incident radiation = 2000P

Answers

Option c is correct. The steel beam d (0.5 x 0.5) tested showed the least deflection. Beam deflection refers to the state in which a beam has changed from its initial shape as a result of a force, load, or weight.

Beam deflection refers to the state in which a beam has changed from its initial shape as a result of a force, load, or weight. Obtaining equations that allow us to accurately calculate beam deflections in a variety of real-world situations is one of the most significant uses of beam deflection. Analysis of statically indeterminate beams also takes into account deflections.

In terms of structural engineering, deflection is the movement of a beam or node from its initial position as a result of loads and forces acting on the member. It is also referred to as displacement and can result from externally applied loads as well as from the structure's own weight and the force of gravity that applies to it.

the average power developed by a motor as it lifts a 400-kilogram mass at a constant speed through a vertical distance of 10 meters in 8 seconds is 5,000 watts.

How do you calculate work done in raising load? ›

The amount of work done is equal to the force applied multiplied by the distance lifted. This can be expressed mathematically as W = F x d, where W is the work done, F is the force applied, and d is the distance lifted. The force applied is equal to the weight of the load being lifted.

How do I calculate work done? ›

Work done = force × distance moved in the direction of the force. is done when energy is transferred from one store to another. Work is also done when a force causes an object to move. When work is done against frictional forces acting on an object, the object's temperature increases.

How do you calculate weight lifting capacity of a motor? ›

Depending on which planet you want to use the device, you can calculate the mass that you can lift against gravitational force. For earth it can be calculated as follows: m = F / g = 22,5 kN / 9,81 m/s^2 = 2293,58 kg.
