Modern Prestressed Concrete furnishes the structural engineer with all the information required for the design of safe, economical prestressed concrete structures.
In the book, designed for self-study, the authors present a simplified procedure for shear analysis in the design of buildings-the arithmetic is reduced to a simple multiplication of a constant (which is given for various points along the member) by the already known applied loads and dimensions of the beam or girder. Complete step-by-step design examples of typical bridge and building members are provided and pertinent parts of applicable codes and specifications are referenced and included in the Appendix. All examples are based on the latest editions of Codes, Specifications and Recommended Practices. Construction methods and equipment are discussed and illustrated in a manner that will enable the engineer to design members which (Continued from page 23)
"OUR

Moving right through the roughest conditions is the Union Brick 403-40 shown above. Four Wheel Drive and Four Wheel Steering gave this unit dependable power and excellent maneuverability.
"SAVED US ABOUT
$250 A WEEK!"
George R. Powell, president of Union Brick Construction Corporation of Virginia Beach, Virginia, has this to say about their Lull 4D3-40 Four-Wheel Drive HIGH LIFT.
"Our experience with the above mentioned unit has been very favorable... to the degree that last fall, on the rugged terrain of our job involving 120 three-story apartments in Greensboro, North Carolina, it saved us approximately $250.00 per week. This machine serviced approximately 18 bricklayers would have required two fork lifts of a two-wheel drive capacity had we not had our Lull on the job.
Later on, when winter set in with the mud, mire and slush, it saved us even more! Nothing slowed our 4D3-40 down, while 75% of the jobs in the area had to close due to inadequate material handling equipment.
We sincerely feel that the investment we have made on this machine puts us in a position to figure jobs and expedite the masonry needs under any working conditions. Our next fork lift will be another Lull Model 4D3-40!"
