A room with inside dimensions of 5x7m is built from block 30x30x30 cm,
using cement sand mortar 1:2.5, the wall thickness is 30 cm.
The room wall height above the footing concrete is 5 m. The room has a
door of size 1.5x2m and a window 3x2m. The room is covered with a slab of
15 cm thick which has a 20 cm extension beyond the outside wall edges all
around. The slab is reinforced with 10 mm bars at 15 cm c/c in both
directions, one bar straight and one bar bent. Estimate:
1. Amount of steel needed for the slab in the short direction only.
2. Amount of blocks needed for construction.

The rectangular block below has front-face dimensions of 10 cm by 4 cm, with a depth of 3 cm.(Figure 1) You will be asked to treat this object as an electrical resistor. Rank the block based on its electrical resistance along the three illustrated coordinate directions (x, y, and z). Rank from largest to smallest. To rank items as equivalent, overlap them. PART B: If all of the dimensions of the block double (to become 20 cm wide, 8 cm...

A thermometer is taken from an inside room to the outside, where the air temperature is −15° C. After 1 minute the thermometer reads 13° C, and after 5 minutes it reads −1° C. What is the initial temperature of the inside room? (Round your answer to two decimal places.) c = ?

A cement block accidentally falls from rest from the ledge of a 51.7-m-high building. When the block is 18.7 m above the ground, a man, 2.00 m tall, looks up and notices that the block is directly above him. How much time, at most, does the man have to get out of the way? Number Units

An adiabatic dehumidifier is used to extract excess moisture from the air inside your hostel room with dimension 8 x 6 x 3 m3 . The room was initially at a dry bulb temperature of 30 oC, 70 % relative humidity is to be humidified to 40 % relative humidity. a) Sketch the process in the phsychrometric chart provided b) Estimate the adiabatic saturation temperature of the entrance air and the final temperature (dry bulb) of the air. c) Calculate...

A road embankment will be constructed using clayey sand from a local borrow excavation. The embankment has a volume of 100,000 cubic meters. Specifications require the soil to be compacted to at least 95 percent of the maximum dry density obtained in a Standard Proctor test (i.e., relative compaction, RC greater than or = 95%). It is estimated that the as-constructed embankment will be at an average RC of 97% since the contractor must meet or exceed this specification. Standard...

Load the USArrests sample dataset from the built-in datasets (data(USArrests)) into R using a dataframe (Note: Row names are states, not numerical values!). Use the kmeans package to perform a clustering of the data with increasing values of k from 2 to 10 - you will need to decide whether or not to center/scale the observations - justify your choice. Plot the within-cluster sum of squares for each value of k - what is the optimal number of clusters? Use...

You raise plants in a controlled growth room, using seeds collected from a natural population. You measure leaf length of adult plants, select the plants with longest leaves, and raise their offspring in the growth room. You find that leaf length in the second generation is 10 cm longer than in the first generation. Using seeds from the same population, you do the same experiment in a field environment, applying the same strength of selection. You find that leaf length...
