PROBETA ROSCADA

Datos

Ø = 13 mm

Lo = 70 mm

Lf = 72,6 mm

Øf = 7 mm

dx = Lf- Lo V = - Ey/Ex

dx = 72.6 mm- 70 mm -Ey= v * Ex

dx = 2.6 mm -Ey= 1/3 * 0,01230 mm/mm

-Ey=-0,01230mm/mm

Ex = dx/Lo V = dy/Øo

Ex = (2.6 mm)/(70 mm) Ø* Ey= dy

Ex= 0.03714 mm/mm dy= (13mm)(-0,01230mm/mm)

dy= -0,16094 mm

BARILLA CORRUGADA

Datos

Ø = 15,85 mm

L = 1102,7 mm

Lo = 623 mm

Lf = 1112,5 mm

dx = Lf- Lo V = - Ey/Ex

dx = 1112,5 mm- 623 mm -Ey= v * Ex

dx = 489,5 mm -Ey= 1/3 * 0,785 mm/mm

-Ey = 0,2616mm/mm

Ex = dx/Lo V = dy/Øo

Ex = (489,5 mm)/(623 mm) Ø* Ey= dy

Ex= 0,785 mm/mm dy= (15,85mm)(-0,2616mm/mm)

dy= - 4,146 mm

BARRA LISA

Datos

Øo = 9,84 mm

Øf = 4,7 mm

L = 1000 mm

Lo = 562 mm

Lf = 572 mm

LT de deformación= 1016,4 mm

Deformación Longitudinal

dx = Lf- Lo V = - Ey/Ex

dx = 572 mm- 562 mm -Ey= v * Ex

dx = 10 mm -Ey= 1/3 * 0,01779 mm/mm

-Ey = - 0,00593 mm/mm

Ex = dx/Lo Ey = dy/Øo

Ex = (10 mm)/562mm Ø* Ey= dy

Ex= 0,01779mm/mm dy= (-0,0059mm)(-9,04mm/mm)

dy= - 0,0583 mm
