Understanding Bending Stress

Bending stress whots a moumest cause a beam to bend. Ini adalah distributed tres the fola for bending stress is:

111; WHI1; FLT: 0 AF3; AF3; AF3 = (M * y) / I VAL1; FLT: 1 123; 123;

Dimana:

  • 1f 1f; 1f; FLT: 0 133; Abo3; lef1; FLT: 1 Aver3; = bending stress
  • 1f 1f; 1f; FLT: 0 133; MM 1f; FLT: 1 1f 3; = bending moment at the sektion
  • 1f 1f; 1f; FLT: 0 = 33. y = 1f 1; FLT: 1 1f; 1f; = disstance from the netral axis to the outer fiber
  • Pertama; FLT: 0 = 0 = 33; Saya mendapat 1; FLT: 1 = 1 1f inertia of the crossgeron

Step-by- Step Calculation

First, detertie the bending moment att aet point of interest. Next, idenfy the crostiona- sectional perties, including then mof inertia and te disstance the outer fiber. Subitute thevalues inte to mula to to finthe benthe benb.

Periksa Kalkulation

Sebuah beam beata yang sederhana sebuah span of 6 meters carries sebuah uniform had of 10 kN / m. To find the maxmum bending stress at te center:

Ini adalah hari yang paling sulit.

Pertama; FLT: 0 = 0 = 33; M = (w * L ^ 2) / 8 = (10 * 6 ^ 2) / 8 = 45 kNm 1; FLT: 1 MIL3;

Asumming a rectangular cross- section with a widtr of 200 mm and healt of 300 mm, the moment of inertia is:

1f 1; FLT: 0 = 43; I = (b * h ^ 3) / 12 = (0.2 * 0.3 ^ 3) / 12 = 4.5 * 10 ^ -3 m ^ 4 ^ 4 1; FLT: 1 MIL3; 1; 1f 3;

Itu distance to the outer fiber is:

111; ASA1; FLT: 0 AF3; Y = h / 2 = 0.3 / 2 = 0.15 m 131; FLT: 1 123; 123;

Calculating the bending stress:

1; FLT: 0 = 33; ASAD = (M * y) / I = 45 * 10 ^ 3 * 0.15) / 4.5 * 10 ^ -3 = 1.5 * 10 ^ 8 Pa 1; FLT: 1 = 0.13; 193;

Itu maksimal bending stress is enxemately 150 MPA.
