The dump truck consists of a chassis and a tray, with centers of gravity at G1 and G2, respectively. With the tray down, the axle loads (normal forces at A and B) are 41 900 lb each. When the tray is in the raised position, the rear axle load increases to 48 700 lb. Compute the weight of the chassis, the weight of the tray, and the distance x.
What is the maximum column load in kips that could be placed on a 4-ft square temporary footing on a sand for which the standard resistance is about N=15 and the water table is at the surface? A factor of safety of 2 is to be maintained against beari..
Plot the adiabatic flame temperature as the percent excess air varies from 10 to 100 percent.
two isotropically consolidated undrained (ciu) triaxial tests, CU1 triaxial tests, CU1 and CU2, were conducted on a normally consolidated (Nc) clay under effective consolidation stresses of 100 and 200 kPa respectively.
A heat exchanger brings 10 kg/s water from 100?C up to 500?C at 2000 kPa using air coming in at 1400 K and leaving at 460 K. What is the second law efficiency?
Given the data below for two alternatives, find the better alternative, if MARR is 8%. alt A |alt B Initial cost $10,000 |$15,000 maintenance cost/ year $1,000 |$500
At the inlet, the pressure is 6 MPa, the temperature is 500 degrees C, and the velocity is 20 m/s. At the exit, the pressure is 0.5 MPa, the quality is 0.95(95%), and the velocity is 75 m/s. The turbine develops a power output of 2500kW.
physics two skaters with masses of 65 kg and 45 kg respectively stand 8.0 m apart each holding one end of a rope. if
Also determine the temperature at the final state in part (b).
Some total station settings can be entered once and then are seldom changed, while other settings must be changed each time the instrument is set up. Prepare two lists of instrument settings, one for each instance.
A “Cold Air-Standard Brayton cycle” gas-turbine power plant delivers a net power output of 60 MW to an electric generator. The compressor intake temperature is 300 K and the maximum temperature in the cycle is 1200 K.
A confined aquifer 30.0m thick has been pumped from a fully penetrating well at a steady rate of 5,000 m^3/day for a long time. Drawdown at an observation well 15m from the pumped well is 3.0 m and a drawdown
A piece of corroded steel plate was found in a submerged ocean vessel. it was estimated that the original area of the plate was 62.5cm 2 and approximately 2.8k had corroded away during the submersion. Assuming a corrosion penetration rate of 5.1mm/yr..
