The supporting structure of the billboard is attached to the ground by a pin at B, and its rear leg rests on the ground at A. Friction may be neglected. Point G is the center of gravity of the billboard and structure, which together weigh 2800 lb. To prevent tipping over in high winds, a 2370-lb weight is placed on the structure near A, as shown.
(a) Compute the magnitudes of the reactions at A and B if the wind load on the billboard is q = 120 lb/ft.
(b) Find the smallest wind load q that would cause the structure to tip over.
Derive a relation for the COP of the two-stage refrigeration system with a flash chamber as shown in Fig. 11-12 in terms of the enthalpies and the quality at state 6. Consider a unit mass in the condenser.
Literature Review for the materials used in the construction of public swimming pools - After each paragraph must put the reference in a "Harvard reference system"
The four coplanar forces are acting at a point as shown in the diagram. Determine the resultant in magnitude and direction analytically and graphically.
The field measurements (in feet) for an irregularly shaped paved area are shown in Figure 17.21. Calculate the area of pavement to the closest square yard.
You must submit a valid design to me before you will receive your building materials. I will not grade your design based on whether it will support the necessary load. I am only approving it as to whether it is a design that meets the building req..
Drawdown data from an observation piezometer near a well used for a pumping test with constant pumping rate is plotted on a semilog plot vs. time (the time axis, on the horizontal, is on a log scale).
calculate the magnitude of the force on the piston pin A for the crank angle θ = 90° (Suggestion: Use the alternative moment relation, Eq. 6/3, with B as the moment center.)
The results are Party 1, DE= 12.46 +/- 0.04ft, Party 2, DE= 12.43 +/- 0.03 ft, Party 3, DE= 12.50+/-0.06 ft. What is the weighted differance in elevation between the two benchmarks ( nearest 0.001 ft)
A car is traveling along a road at a uniform velocity when at time zero the driver recognizes a hazard. At a moment 0.8 seconds later the driver brakes her vehicle , resulting in her vehicle sliding 90 ft in the same direction
The load in the bucket of a skid steer loader is 600 lb with its center of gravity at G. For the position shown, determine the forces in the hydraulic cylinders AC and DE.
A particle of mass 200kg is lifted up vertically by a force of 104N. Assuming the acceleration due to gravity is 10meterper.secondsquare, write a program to calculate the upward acceleration of the particle.
A computer CPU chip consists of 50 g silicon, 20 g copper, and 50 g polyvinyl chloride (plastic). It heats from 15?C to 75?C as the computer is turned on. How much did the entropy increase?
