Answer / hari prasad
When a metal is subjected to a load (force), it is
distorted or deformed, no matter how strong
the metal or light the load. If the load is small, the
distortion will probably disappear when the
load is removed. The intensity, or degree, of distortion is
known as strain.

Answer / karthick
change in the dimension of a material to the original
dimension.
| Is This Answer Correct ? | 7 Yes | 1 No |
strain=chnage in lengths/original length
| Is This Answer Correct ? | 7 Yes | 2 No |
Answer / sprajapati21
If i have x dimention material and i applied force on it
than the dimention increase x + l
and origanal dinmention x
stain = deformation/original dimention = l/x
and stain have no unit of measurement
| Is This Answer Correct ? | 4 Yes | 0 No |
Answer / manoj negi
strain is the measure of deformation........i.e ratio of change in dimension to orignal dimension
| Is This Answer Correct ? | 3 Yes | 0 No |
Answer / awinash kumar
it is a unitless quantity and it is the ratio of change in
lenth and original length.
| Is This Answer Correct ? | 2 Yes | 0 No |
Answer / umesh parmar
Strain is deformation per unit length.
Deformation occurs when any external load is applied to
subjet.
| Is This Answer Correct ? | 2 Yes | 0 No |
Answer / mohan
Its change change in length by Actual length
no units
because meter by meter is zero.

2. Dry saturated steam at 3.5 bar is expanded through a convergent nozzle to 2.2 bar. The exit area is 5 sq. cm. Calculate the exit velocity and mass flow rate, assuming isentropic expansion and super saturated flow. b) A cast iron cylinder head is fastened to a cylinder of 750mm bore with 12 stud bolts. The maximum pressure inside the cylinder is 3 Mpa. The stiffness of part is thrice the stiffness of the bolt. What should be the initial tightening load so that the point is leak proof at maximum pressure? Also choose a suitable bolt for the above application 2 The propeller shaft of a marine engine is to transmit 600 kW at 1200 rpm, without a significant bending. The efficiency of the propeller is 88% at 32 knots ( 1 knot = 1085 km/hr). If the slenderness ratio is less than 50 and the permissible shear stress should not exceed 65 Mpa. Determine the diameter of shaft. 3 A semi-elliptic leaf spring consists of two extra full-length leaves and six graduated length leaves, including the master leaf. Each leaf is 7.2 mm thick and 65 mm wide. The centre-to-centre distance between the two eyes is 1.3m. The leaves are pre-stressed in such a way that when the load is maximum, stress induced in all leaves are equal to 380 N/mm sq. Determine the maximum force that the spring can withstand
