Heating Element: Nichrome wire

- Electrical resistivity by 20° = 1,05 Ωmm2/m
- Maximum using temperature = 1150 ° C
- not magnetic
-Melting point = 1440 °C

Calculations screw 2

Cilindrical headed screw

- Dk = 5.5 mm
- k = 2
- l = 12 mm

--> d = M3

F2*P = F1*d*pi

F1 = aandraaikracht

F2 = Spilkracht

P = Spoed

Calculations screw 1

Screw:
- Type H
- m = 2 mm
- f = 0.5 mm

---> d  = M2

F2 *P = F1*d*pi

F1 = aandraaikracht

F2 = spilkracht

P = Spoed
