Structural Engineering

Structural engineering is a field of engineering that deals with the analysis and design of structures that support or resist loads. Structural engineering is a speciality within civil engineering, although it can also be studied in its own right. Structural engineers are commonly involved in the design of buildings and large non-building structures but they can be involved in the design of machinery, medical equipment, vehicles or any item where structural integrity affects the item’s function or safety.

Structural engineering theory is based upon physical laws and empirical knowledge of the structural performance of different materials and geometries. Structural engineering design utilizes a number of simple structural elements to build complex structural systems. They are responsible for making creative and efficient use of funds, structural elements and materials to achieve these goals.

The history of structural engineering contains many collapses and failures. Sometimes this is due to negligence and other times due to structural failures. The results of these inquiries have resulted in improved practices and greater understanding of the science of structural engineering. 

Nursing Home Design

Hospitals are not the only healthcare facilities. Now due to various reasons in the U.S. population, government policy, technology and finance, we have ambulatory surgery centers, nursing homes, independent living facilities, imaging centers, mental health facilities, rehabilitation centers, wellness centers, medical office comp

Static Engineering - Beam Question

I am completing a work pack as preparation for an exam coming up. The questions have moved onto beams and the question is very dissimilar to the examples I've been given and I am having trouble progressing, and unsure of any answers I produce. The question is separated into 5 parts. I have linked the question in the picture b

Beam deflection

Q.1 Derive an expression for the deflection due to shear for a cantilever beam of constant rectangular cross section, under action of a point load, P at free end. Q.2 Show how the max shear stress occurs at the neutral axis and a value of 3/2 x average shear stress on the section. Q.3 If length of cantilever is 2m, P=100K

Pumping works in the City of London

(See attached file for full problem description) --- The City of London has grown significantly, so city planners have decided that a second water supply line from Grand Bend. ---

Bearing stress12

A 10 kip axial load is applied to a short wooden post which is supported by a concrete footing resting on undisturbed soil. How would I determine the maximum bearing stress on the concrete footing, as well as the size of the footing for which the average bearing stress on the soil is 20 psi?

Calculating maximum load of a hovering helicopter

The helicopter can produce a maximum downward air speed ( v = 24 m/s ) in a slipstream of a diameter ( D = 9 m). Knowing that the weight of the helicopter and the crew is ( 15 kN ) and assuming air density rho = 1.21 kg/m^3 ), determine the maximum load that helicopter can lift while hovering in midair. ( 29.3 kN ) Thank you

Shear and Bending Moment

A 10ft beam has applied forces F1 and F2 as shown. The influence functions for the shear and bending moment at point B are als shown. For forces F1=10lbs and F2=20lbs, how do I find the shear and bending moment at point B? See the attached file.

Formulate a Linear Program for Blend Mix at Bluegrass Distillery

The Bluegrass Distillery produces custom-blended whiskey. A particular blend consists of rye and bourbon whiskey. The company has received an order for a minimum of 400 gallons of the custom blend. The customer specified that the order must contain at least 40% rye and not more than 250 gallons of bourbom. The customer also spec

Text book Management science 7 ed by Bernard Taylor

Solve the following linear programing model graphically. Maximize Z= 5x1 + 8x2 subject to: 3x1 + 5x2 <= 50 2x1 + 4x2 <= 40 x1 <= 8 x2 <= 10 x1,x2 > 0 Transform this model into standard form and indicate the value of the slack variables at each corner point solution.

Dynamics - Position

Just in case you can't read the writing on the attached file it states: Two monkeys of equal weight are hanging in equilibrium at the ends of a rope passing over a relatively light pulley for which the bearing friction can be neglected. Then the monkey on the right begins to climb the rope while the monkey on the left simply ho

Dynamics: Velocity of a Sphere After a Collision

Two spheres each of mass m, can slide freely on a frictionless, horizontal surface. Sphere A is moving at a speed Vo=16 ft/s when it strikes sphere B which is at rest and the impact causes sphere B to break into two pieces, each of mass m/2 Knowing that 0.7s after the collision one piece reaches point C and 0.9s after the collis

Sketch a streamline, pathline, and streakline

For a given flow the velocity from time t=0 to t=5s was u=2 m/s, v=0. Then from t=5s to t=10s the velocity was u=+3 m/s, v=-4 m/s. A dye streak was started at t=0, and a path was traced from that same point at the same time. Draw to scale the streakline, pathline, and streamlines at t=10s. Please solve and explain. I have see

Determining Distance Traveled Up a Slope

A 37kg object is placed onto a coil spring which has been compressed 43mm. The force used to compress the spring was 35KN.The spring and the object are on the same incline plane angled at 21deg from the horizontal. If the coefficient of friction is 0.37,how far will the block travel up the slope?
