The cutting force in a sheet metal blanking operation depends on which mechanical property of the metal (one correct answer): (a) compressive strength, (b) modulus of elasticity, (c) shear strength, (d) strain rate, (e) tensile strength, or (f) yield strength? 4.
2. Design of Welded Connections
let weld in a hole or slot calculated from this length is greater than the area calculated from 2.5.1, then this latter area shall be used as the effective area of the fillet weld.

(d) Determine the tensile strength of this alloy. (e) What is the approximate ductility, in percent elongation? (f) Compute the modulus of resilience. Solution This problem calls for us to make a stressstrain plot for aluminum, given its tensile loadlength data, and Bolted Joint Analysis  MechaniCalcPer Shigley, the proof strength is approximately equal to 85% of the tensile yield strength, S ty. Based on S proof = 0.85S ty, the recommended preload force as a function of yield strength is: Considering that the above values are conservative, a general rule of thumb is to preload the fastener to 2/3 of the yield strength (i.e., % yld = 66.7%).
Chapter 3: Machinability of Metals  Cutting Tool definition of yield strength chegg Hole drilling
Yield strength is measured just prior to the point before permanent deformation takes place. Yield strength is stated in pounds per square inch (PSI) and is determined by dividing the load just prior to permanent deformation by the cross sectional area of the test specimen. Comstock Lode  WikipediaThe Comstock Lode is a lode of silver ore located under the eastern slope of Mount Davidson, a peak in the Virginia Range in Virginia City, Nevada (then western Utah Territory), which was the first major discovery of silver ore in the United States and named after American miner Henry Comstock. Definition of Bazin Formula  Chegg definition of yield strength chegg Hole drillingBazin formula is used to determine the average velocity of the fluid. It is normally used in open channel flow system. It relates the variables velocity, radius with coefficients such as roughness coefficient and discharge coefficient. When the radius and coefficients are known, then the average velocity of the flow can be calculated.
Definition of Yield Strength  Chegg definition of yield strength chegg Hole drilling
Yield Strength. Yielding is a property which comes visible when a tensile pressure is applied continuously on any piece of material, or in fact for any mind undergoing tension, resists for some time up to its proportionality limit, and after some time, material piece certainly yields or mind give up, and starts moving plastically without any definition of yield strength chegg Hole drilling Design of Bolts in ShearBearing Connections per AISC LRFD definition of yield strength chegg Hole drillinga) HighStrength Bolts: The three basic types of high strength listed in the LRFD are: ASTM designations A325, F1852, and A490. The new ASTM specification F1852 refers to the fasteners frequently referred to as tension control, TC, twistoff, or torqueandsnap fasteners. HighStrength bolts range in diameter from to 1 in.

Lecture 9 Introduction to Rock Strength David Hart definition of yield strength chegg Hole drilling
The peak stress is the strength of the rock. It may fail catastrophically if the load frame is soft. Example below is for a stiff frame. The compressive strength of rock is a function of the confining pressure. As the confining pressure increases so does the strength.

The hole is a blind hole at a depth of 60 mm and the point angle is 118.
