A rectangular beam, simply supported over a span of 4m, is carryinga uniform distributed load of 5kN/m and a concentrated load of 5kNat the center of the beam. Find the dimensions of the beam, ifdepth of the beam is 2.5 times its width. Take maximum bendingstress in the beam section as 75MPa
a) Depth of Beam b) Width of Beam
An asphalt concrete mixture includes 94% aggregate by weight. The specific gravities of aggregate and asphalt are 2.65 and 1.0, respectively. If the bulk density of themix is 147 pcf, what is the percent voids in the total mix
Describe the basic principle of differential GNSS positioning and the difference between real time differential GNSS and post processed differential GNSS.
a 20 kg block slides along the rough surface for which the coefficient of kinetic friction is 0.2. The block strikes a nonlinear spring with a speed of v=4.5 m/s. The spring is termed "nonlinear" because it has resistance of Fs=ks^2

A 3.60-g lead bullet at 28.0 degrees C is fired at a speed of 230 m/s into a large block of ice at 0 degrees C, in which it embeds itself. What quantity of ice melts?
If all the posts have the same original lenth before they are loaded, determine the average normal stress developed in each post when post C is heated so that its temperature is increased by 20 degrees F.
identical bricks 0.1m wide and weighting 2kg are placed on a plate assume the plate has neligible weight. calculate the
At a certain location along the span, a reinforce concrete beam section with d=14 in. and b=10 in. is subject to a design shear of Vu=50k. Using No.4 stirrups, compute the required stirrup spacing at the given location. assume F'c=3 ksi and Fy=40 ..
