3) ンド Three forces are applied to the machine component ABD as showr Knowing that the cross section containing point H is a 20 x 40-mm rectangle determine the principal stresses and the maximum shearing stress at point E 50 mm 150 mm 40 mm 0.5 kN 20 mm 3 kN 160 mm 2.5 kN

Q1: A 6-kips force is applied to the machine element AB as shown. Knowing that the uniform thickness of the element is 0.8 in., determine the combined normal stresses at points (a) and (f). 1.5 in. 1.5 in. B a ob С 8 in. □e 0 f 8 in. 6 kips 35° 8 in.

Knowing that the magnitude of the horizontal force P is 8 kN, determine the normal stress at point A. 30 mm 24 mm 45 mm 15 mm 80.6 MPa O 102.8 MPa O 80.6 MPa O - 102.8 MPa O None of the options

The cantilever beam AB will be installed so that the 60-mm side forms an angle β between 0 and 90° with the vertical. The 660-N vertical force P is applied at the center of the free end of the beam. Determine the value of β for which the normal stress at point a is a maximum and the corresponding value of that stress. (Round the final answer to two decimal places.)
