For the beam shown below, W = 120 kN/m, determine the absolute maximum shear stress developed in the beam at points A and B shown on the beam cross-section using the formula.

Note: Do NOT round off any values until the final answer.

What is the magnitude of the maximum shear force V in kN?

Do NOT include any units.

Give the answer to 2 decimal place.

What is the value of τ at B in the cross-section in MPa?

Do NOT include any units.

Give the answer to 2 decimal place.

With reference to the shear stress equation as it appears on the Figure in the question, what is the value of Q at A in mm³?

Do NOT include any units.

Present your answer using exponential format/scientific notation with 4 significant figures. 

e.g. 222.0E4 or 2.220E6

What is the value of τ at A in the cross-section in MPa?

Do NOT include any units.

Give the answer to 2 decimal place.

Assume point B to lie just above the location where the member widens, so t = 100 mm.

What is the value of Q here in mm³?

Do NOT include any units.

Present your answer using exponential format/scientific notation with 4 significant figures. 

e.g. 3.300E6 or 33.00E5

What is the value of I in mm⁴?

Do NOT include any units.

Present your answer using exponential format/scientific notation with 5 significant figures. 

e.g. 1230.0E6 or 12.300E8
