Development length is the minimum length of reinforcement required to transfer the stress from steel to concrete.
It is the length of the bar required to be embedded in the concrete to transfer the stress.
It depends on the diameter of the bar, type of concrete, and the bond strength between steel and concrete.
It is calculated using the formula Ld = (φ × fy × As) / (4 × τbd × σst)
For example, for a 20mm diameter bar in M...

It can also be used to prevent soil erosion and improve the ...
Bearing capacity of soil can be increased by improving soil compaction, adding reinforcement, or using ground improvement techniques.
Improving soil compaction by using heavy machinery or adding water to the soil
Adding reinforcement such as geotextiles or geogrids to increase soil strength
Using ground improvement techniques such as soil stabilization or deep soil mixing
Replacing weak soil with stronger soil or using pil...
The amount of steel needed for a 1000sqft slab depends on the thickness of the slab and the spacing of the steel bars.
The thickness of the slab will determine the amount of steel needed.
The spacing of the steel bars will also affect the amount of steel needed.
A typical 4-inch thick slab may require around 100-120 steel bars per 1000sqft.
The size and type of steel bars used will also impact the amount needed.
BOQ stands for Bill of Quantities, which is a document that lists all the materials, labor, and equipment needed for a construction project.
BOQ is a detailed document that helps in estimating the cost of a construction project.
It includes a list of all the materials, equipment, and labor required for the project.
BOQ is prepared by a quantity surveyor or an estimator.
It helps in comparing the actual cost of the project ...
Puff panel is a type of insulated panel made of two metal sheets with a foam core in between.
Puff panels are commonly used in construction for walls, roofs, and ceilings.
They provide excellent insulation and are lightweight, making them easy to install.
Puff panels are also fire-resistant and have good sound insulation properties.
Examples of applications include cold storages, clean rooms, and industrial buildings.
Putty work involves filling gaps and cracks in walls to create a smooth surface for painting or wallpapering.
Clean the surface to be puttied
Apply putty to the gaps and cracks using a putty knife
Smooth out the putty with a wet sponge or sandpaper
Allow the putty to dry completely before painting or wallpapering
Repeat the process if necessary for a smooth finish

The present CEO is John Smith.
The present CEO is John Smith.
John Smith has been the CEO since 2015.
Under John Smith's leadership, the company has experienced significant growth and expansion.
John Smith has a background in engineering and has previously held executive positions in other companies.
Yes, I know C language. Here's a program to print numbers from 1 to 10 excluding 5.
Use a loop to iterate from 1 to 10
Inside the loop, check if the current number is equal to 5
If it is not equal to 5, print the number
The question was about finding the average of a set of numbers.
I approached the problem by first summing all the numbers in the set.
Then, I divided the sum by the total number of elements in the set to find the average.
I used a loop to iterate through the set and keep track of the sum and count of elements.
Find sum of all numbers formed from root to leaf path in a binary tree
Traverse the binary tree using DFS
At each leaf node, add the number formed from root to leaf path to a sum variable
Return the sum variable
Time complexity: O(n)
Example: For a binary tree with root value 1, left child 2 and right child 3, the sum would be 12 + 13 = 25
Given a string, print all possible strings that can be made by placing spaces (zero or one) in between them.
Use recursion to generate all possible combinations of spaces
For each recursive call, either add a space or don't add a space between the current character and the next character
Base case is when there are no more characters left to add spaces between
Time complexity is O(2^n) where n is the length of the string
Preorder traversal without recursion
Use a stack to keep track of nodes
Push right child first and then left child onto stack
Pop top of stack and print value
Repeat until stack is empty
Find longest continuous patch on a 12 km road with updates in patches
Maintain a variable to keep track of current patch length
Update the variable whenever a new patch is added
Maintain a variable to keep track of longest patch so far
Compare current patch length with longest patch length and update if necessary
Use a sorted data structure like a binary search tree to store the patches for efficient search
Time complexity: ...
Find median of an unsorted array.
Sort the array and find the middle element
Use quickselect algorithm to find the median in O(n) time
If the array is small, use brute force to find the median
Find 'k' elements closest to a given number from a stream of characters.
Use a priority queue to keep track of closest elements.
Update the queue as new characters come in.
Return the 'k' closest elements from the queue.
Design a data structure with O(1) insert, remove, find-max, and delete-max operations.
Use a doubly linked list to maintain the elements in sorted order.
Use a hash table to store the pointers to the nodes in the linked list.
Maintain a pointer to the maximum element in the hash table.
Update the pointers in the hash table when inserting or removing elements.
Update the maximum pointer when deleting or inserting the maximum
Check if a given linked list is a palindrome.
Traverse the linked list and store the values in an array.
Compare the first and last elements of the array, then move towards the center.
If all elements match, the linked list is a palindrome.
Alternatively, use two pointers to find the middle of the linked list and reverse the second half.
Compare the first half with the reversed second half to check for a palindrome.
