In engineering, shear strength is the strength of a material or component against the type of yield or structural failure when the material or component fails in shear.A shear load is a force that tends to produce a sliding failure on a material along a plane that is parallel to the direction of the force. When a paper is cut with scissors, the paper fails in shear.

Aug 29, 2016· First, you need to find the capacity of the beam, moment or shear, whichever smaller governs. If the beam is long and slender, your governing capacity is likely moment, if the beam is short and stocky, your governing capacity is likely shear. For ...

Stopping (Braking) Distance Calculator Common questions that arise in traffic accident reconstructions are "What was the vehicle's initial speed given a skid length?" and "What distance is required to stop from this speed?". You will be able to answer these questions by simply entering the road surface type, units, and speed or distance below.

This calculator may give you a rough idea of the deflection of metal tubing, but it's not accurate enough to do any more than estimate it. If the deflection is large enough to permanently bend the tube, then all bets are off. The steel weights are tweaked for mechanical tubing, …

Lateral Load Capacity of Piles M. T. DAVISSON, Department of Civil Engineering, University of Illinois, Urbana Pile foundations usually find resistance to lateral loads from (a) passive soil resistance on the face of the cap, (b) shear on the base of the cap, and (c) passive soil resistance against the pile shafts. The latter source is

CIP 42- Thermal Cracking of Concrete WHAT is Thermal Cracking? WHY Does Thermal Cracking Occur? Thermal cracking occurs due to excessive temperature dif-ferences within a concrete structure or its surroundings. The temperature difference causes the cooler portion to con-tract more than the warmer portion, which restrains the con-traction.

4.1 This test method is used to determine the flexural strength of specimens prepared and cured in accordance with Test Methods C42/C42M or Practices C31/C31M or C192/C192M.Results are calculated and reported as the modulus of rupture.
