What is metal fatigue and what is thought to cause it?
Stress of a steel beam, for example, which can overload and bend eventually, if the load on the beam is greater than the design limits of that beam.Heat can also stress metal to the point of changing shape, losing strength and becoming brittle enough to fracture.2nd AnswerThe above answer is actually describing a load that exceeds the materials ultimate stress. Fatigues does not cause the part to bend.Stress is a repeated application of a load that is below the ultimate design load that results in microscopic distortion of the metal and can induce cracks. These cracks will eventually grow under repeated load applications and resulting in failure of the part.All material is tested for its fatigue Endurance Limit. If you design the part so that it will have repeated loads below this Endurance Limit OR design it so that it does not see high cycles of load application, then the part can be designed so that it will not fatigue.
Why metals break on dynamic load but not on static load of same magnitude?
That isn't necessarily true. If the metal is under repeated dynamic loading, it becomes a matter of material fatigue and not strength. For instance, if you bend a paper clip back and forth repeatedly, it becomes easy to break. The material properties have changed (more brittle) due to the repeated dynamic load.In the case of impact or blast loading, it is actually the opposite. Materials often have the ability to withstand much larger loads than they could statically, but for very short durations (on the scale of milliseconds).because i said so.Dynamic load- Any load which is nonstatic, such as a wind load or a moving live load.Static Load - Any load, as on a structure, which does not change in magnitude or position with time
Bear the load or bare the load?
Bear the load. Bare the load would be to uncover the load...
What is difference between impact load and sudden load?
sudden load differ from impact load by the velocity of loading
How many types of load cell?
I think there are 4 types of load cells they are Pancake Load CellS ,Beam Load CellLoad, ButtonSingle and Point Load Cell.
What repeated digits are in 10 to the 100th power?
A serious load of zeros.
What is a group of repeated movements performed continuously with a given weight load?
set

What is the meaning of inflammation or vascular compromise?
inflammation represents the body's response to tissue injury caused by pressure , friction , repeated load or overload and external trauma

What is a function of neutral wire?
to complete the circuit and back to power supply
What is a sentence for the word repeated?
When the answer was repeated, she understood it better.
What is the load which can be lifted safely by an employee in a workplace?
The load that can be safely lifted by one person in a workplace depends on how the person is called upon to lift it and how they will handle it once in their hands. Reaching out, twisting, or lifting or placing below the knuckles or above the shoulders significantly reduces the maximum safe load. Research conducted by NIOSH suggests that in the best conditions, the maximum safe load for repeated lifting is not greater than 45 pounds (20.5 Kg). If twisting or reaching is involved, this can be reduced to 12 pounds (5.5 Kg) or even less.
What does repeated mean in math?
Division. Multiplication is repeated addition.
What is repeated multipliction?
Repeated multiplication is called raising to a power.
