*7-16. The beam has a square cross section and is made of wood having an allowable shear stress of Tallow = 1.4 ksi. If it is subjected to a shear of V = 1.5 kip, determine the smallest dimension a of its sides. Problem 7-16 V = 1.5 kip

The solid shaft of radius c is subjected to a torque T at its ends. Show that the maximum shear strain in the shaft is gmax = Tc>JG. What is the shear strain on an element located at point A, c>2 from the center of the shaft? Sketch the shear strain distortion of this element.

The beam has a square cross section and is made of wood having an allowable shear stress of Tallow= 1.4 ksi. If it is subjected to a shear of V= 1.5 kip, determine the smallest dimension a of its sides. Sketch the shear stress distribution acting across the beam's cross section. Hint: Construct the stress distribution in 2D similar to in-class examples, rather than isometrically similar to the textbook examples for clarity. V = 1.5 kip

The shaft is subjected to the concentrated forces as shown in the figure below. There is a journal bearing at A and a thrust bearing at B. The allowable bending stress is σallow = 210 MPa. Determine, to the nearest mm, the smallest allowable diameter of the shaft.
