A shear force, S₂ is applied. This results in shear flow, shown with red arrows, which has the following values:
• Shear flow in part 13, just before point 3 - 38 N/mm
Shear flow in part 23, just before point 3 = 44 N/mm
Shear flow in part 43, just before point 3- 44 N/mm
What is the shear stress in part 35, just below point 3?
Express your answer in MPa, to 2 decimal places but without the units included. You have a 3% margin of error.

- Suppose that the length of the steel bar is measured by a number of different observers and following set of 11 measurements is recorded as set A (units mm): 398, 420, 394, 416, 404, 408, 400, 420, 396, 413, 330. Next the measurements are taken using different ruler to produce measurement set B: 409, 406, 402, 407, 405, 404, 407, 404, 407, 407, 408.
