Problem 1 Section: An aluminum circular tube AB is connected to a square solid steel shaft CD through gears at B and C. Determine the angle of twist of both shafts and the maximum shear stress in both materials due to the torque applied at B. Assume linear elastic behavior. Diameter of gear at B - 18 in. UVO aluminum 50 k-ft AA TV 50 3 ft. steel 2 ft. Diameter of gear at C-8 in.
Ends A and D of the two solid steel shafts AB and CD are fixed, while ends B and C are connected to gears as shown. Knowing that a 4kN-m torque T is applied to gear B,determine the maximum shearing stress (a) in shaft AB, (b) in shaft CD.
The two 3-ft-long shafts are made of 2014-16 aluminum. Each has a diameter of 1.5 in. and they are connected using the gears fixed to their ends. Their other ends are attached to fixed supports at A and B. They are also supported by bearings at C and D, which allow free rotation of the shafts along their axes. (Figure 1) A torque of T=500 lb-ft is applied to the top gear as shown. Part A Determine the maximum shear...
Problem 1 (25 Points) Two solid steel (6-80 GPa) shafts are connected by the gears shown. Shaft (1) has a diameter of 45 mm, and shaft (2) has an outside diameter of 55 mm and wall thickness 4 mm. Assume that the bearings shown allow free rotation of the shafts. If a 400 N-m torque is applied at gear D, determine (a) the maximum shear stress magnitudes in each shaft. (b) the angles of twist ф, and ф (c) the...
shown in Figure 2. Two circular disks A and B are welded to the ends of both bars. The disks lie in planes disks A and B subjecting the bars to torsion. If the allowable maximum shear stress is 35 MPa and the allowable rate of twist is 3°/m for both bars, determine the smallest outer diameter (D, and Di) of both bars. The shear modulus of elasticity is 39 GPa to the axes of the bars. Forces 15 kN...
Two solid rods have the same length and are made of the same material with circular cross sections. Rod 1 has a radius ?1 and Rod 2 has a radius ?2=?1/2 If a compressive force ?F is applied to both rods, their lengths are reduced by Δ?1 and Δ?2, respectively. The ratio Δ?1 / Δ?2 is equal to The choices are .25, 2., 1., 0.5, 4.
