CALCULOS PRACTICA 6: PUNTOS DE LIGA.

PROMEDIO DE LONGITUD.

X Long= D Ida+ D. reg. / 2

1-2 23.54+23.52/2= 23.54

2-3 45.48+45.46/2= 45.47

3-4 11.45+11.45/2= 11.45

4-5 15.76+15.75/2= 15.75

5-1 50.94+50.92= 50.93

CONOCER EL ERROR LINEAL.

E= X long + D. ida

= X Long – D reg.

E1= 23.53 – 23.54 = 0.01

E2= 45.47-45.48 = 0.01

E3= 11.45-11.45= 0

E4= 15.75-15.76= 0.01

E5= 50.93-50.94= 0.01

CONOCER LA TOLERANCIA LINEAL.

Ti=2e √(2l )/L

T1= 2(0.03)√(2(23.53) )/20= 0.092

T2= 2(0.03)√(2(45.47) )/20= 0.12

T3= 2(0.03)√(2(11.45) )/20= 0.064

T4= 2(0.03)√(2(15.75) )/20= 0.075

T5= 2(0.03)√(2(50.93) )/20= 0.13

2 S-a= s-b= 11.40-2= 9.40

S-c= 11.40-7.40= 4

tan c/2=√((s-a)(s-b)/(s)(s-c) )

tan c/2=√((9.40)(9.40)/(11.40)(4) )= 108® 36’ 52.33’’

A2= 2 7.45 s=2+2+7.45= 11.45

2 S-a=S-b=11.75-2= 9.45

S-c= 11.45-7.45= 4

tan c/2=√((9.45)(9.45)/(11.45)(4) )= 108® 47’ 1.3’’

A3= 2 7.63 S=2+2+7.63= 11.63

2 S-a=S-b=11.63-2=9.63

S-c= 11.63-7.63= 4

tan c/2=√((9.63)(9.63)/(11.63)(4) )= 109® 22’ 59.03’’

A4= 2 6.50 S= 2+2+6.43= 10.50

2 S-a=S-b= 10.50-2= 8.50

S-c= 10.50-6.50= 4

tan c/2=√((8.50)(8.50)/(10.50)(4) )= 105® 21’ 11.88’’

A5= 2 7.51 S= 2+2+7.51= 11.51

2 S-a=S-b= 11.51-2= 9.51

S-c= 11.51-7.51= 4

tan c/2=√((9.51)(9.51)/(11.51)(4) )= 108® 59’ 6.5’’
