What is Secant Modulus?
The secant modulus is the total stress or strain on an object as described by a stress-strain graph. The tangent modulus is the marginal strain.
Strain formula for cylinder in tensile test?
Strain = Extension (m) / Original length (m)
What is the dimension of strain?
it has no dimension
Ride a plane or ride in a plane?
ride in a plane. you would fly a plane
How do you find the original length if you are given the strain and the extended length?
Use the formula Strain=Extension/original length and rearrange to give Original length=Extension/Strain. Substitute the values you have for the strain and the extended length into the equation and voila! Source: Doing A-level (senior high-school in America) Maths and Physics.
Can repetitive strain injury be a serious condition?
yes
How do you measure the force for a plane?
The force acting on a plane can be measured by instruments called strain gauges, which detect the deformation (strain) in the plane's structure caused by applied forces. These measurements can be used to calculate the force applied to the plane in various directions. Flight data recorders and load cells are also used to measure forces on a plane during flight and while on the ground.
What is the difference between dynamic strain aging and strain aging?
Strain aging could be described as " normal wear and tear " or the fatigue that is experienced under normal conditions, whereas Dynamic strain would be an out of the normal range stress condition like a one time over stress condition where the sum of much strain aging is experienced in one " dynamic" occurrence.
What is plane stress condition?
It is a condition in which normal and shear stresses directed perpendicular to the "x-y"plane are assumed to be "zero"
What rhymes with the name Jane?
cane, plain, main, train, plane, crane, strain, lane,
What does it mean strain on the heart?
strain on the heart means that there is some pathological condition causing the heart to work harder. e.g stenosis, emboli, infarction... we can observe this strain by using methods like ECG or echocardiogram.
Why is the theoretical value for modulus of elastricity for mild steel is different from the calculated value?
because it is the ratio of the stress to the strain and in actual condition the strain developed is different from the theoretical .
What condition must exist so that an object placed on an inclined plane will not slide down the plane?
the inclined plane must be very rough
What condition must exist so that an object place on an inclined plane will not slide down the plane?
the inclined plane must be very rough
What is the neutral plane?
The neutral plane is a concept in structural engineering that refers to the plane within a beam where there is no stress or strain resulting from bending. It is the boundary between the tensile and compressive regions of a beam subjected to bending loads.
What has the author O H Narayanan written?
O. H. Narayanan has written: 'Investigation of bulge formation in plane-strain strip drawing'
Assumptions of ultimate load method?
1. Plane sections normal to axis remain plane after bending. This implies that strain is proportional to the distance from neutral axis. 2. Maximum strain in concrete of compression zone at failure is 0.0035 in bending 3. Tensile strength of concrete is ignored. 4. The stress-strain curve for the concrete in compression may be assumed to be rectangle, trapezium, parabola or any other shape which results in prediction of strength in substantial agreement with test results.
