What is the amount of axial stress on a member which is subjected to a sudden load when compared to load applied gradually?
The maximum stress induced in a body due to suddenly applied load is twice the stress induced when the same load is applied gradually
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
What is the difference between mechanical stress and thermodynamic stress?
Mechanical stress is due to the resistance offered by various materials against physical distortion or damage. Thermal stress is caused due to the expansion of materials due to the variations in temperature with respect to reference value.
What strain or pressure in a material due to forces acting on it?
Stress
How do I calculate the exstension in a steel cable that is 8 metres long and has a 500kg weight on it. The Young's modulus of the steel is 210 GPa and the diameter is 7.2mm?
In order to calculate the extension of the cable we must first calculate the strain. Strain is related to Young's modulus using the following relation:E = σA / εAWhere:E = Young's ModulusσA = Axial StressεA = Axial StrainTherefore to calculate the strain, we must first calculate the axial stress in the cable:σA = Force / AreaThe cross sectional area (CSA) of the cable is equal to:CSA = (pi(d2))/4 = pi x r2CSA = pi(0.0036)2CSA = 4.0715x10-5 m2Axial Stress = (500 x 9.81) / 4.0715x10-5σA = 120471449.98 PaAxial Stress = 120.47144998 MPaStrain of cable (εA) = Axial Stress / Young's ModulusεA = 120.471x106 / 210x109εA = 5.736735713x10-4To calculate the extension of the cable:εA = Extension / Original LengthTherefore:Extension = εA x Original Length= 0.0045893885704 m≈ 4.6 mm of extension.
What is the difference between tensile stress and breaking stress?
tensile stress is due to just the tension in the load whereas breaking stress can be due to breaking,shearing or compression!
What is the amount of axial stress on a member which is subjected to a sudden load when compared to load applied gradually?
The maximum stress induced in a body due to suddenly applied load is twice the stress induced when the same load is applied gradually
What is the difference between Bending and Direct Stress?
-> when a structural body gets deviated from its original position or from its centroidal axis due to externally applied load,then it is termed as BENDING->DIRECT STRESS is the stress which act normal to the plane-> stress and bending are the two different things. stress produced by load per area & bending is the effect produced by load and stress.
Where will you find the maximum shear stress in a beam?
The maximum stress occurs where shear load is maximum and maximum stress is at the center of the beam cross section if loaded in shear due to bending. It drops to zero at the top and bottom surfaces. The average stress is load divided by area ; maximum stress is dependent on shape of cross section and is 1.5 times load divided by area at the cross section center for rectangular cross section. For shear due to twist, max shear stress in the outer surface.
What is fracture in mechanics?
Fracture in Mechanics is the event in which an object loses material continuity (it splits in more than one piece) due to the application of a stress load. Said stress load has a consequence in strain, that with the proper values, can induce an object to "fail" in an event called fracture.
What are the causes absenteeism?

What is the dead load and a live load and a dynamic load in a building?
Dead load is the total load of all of the components of the building that generally do not change over time, such as the steel columns, concrete floors, bricks, roofing material etc. Live load is the sum of the dead load plus the "live" occupants and temporary loads, such as staff in the building, desks, chairs, etc. Things that are contained in the building but do not make up its' construction. Dynamic load is loading which changes over time, such as wind pressure on the walls, snow loading on the roof, and even earthquake loads.
What is dynamic failure?
Dynamic failure refers to a sudden and unexpected breakdown or malfunction of a system or component due to external factors such as high stress, overload, or improper operation. This type of failure can occur without warning and can lead to serious consequences if not addressed promptly.

How do you calculate the total investment in a load fund?
To calculate the total investment in a load fund, you multiply the number of shares purchased by the net asset value (NAV) per share. The NAV represents the price of one share of the fund on a given trading day. The result is the total amount of money invested in the load fund.
