Question 21 In the term = LP is equal to The diameter The radius The distance from the center of the cross section to the location of stress being calculated The distance from the edge of the cross section to the centroid Question 22 The torsion formula assumes linear and elastic deformation O True O False Question 23 In the equation Tc/), for a circular shaft, cis equal to: O Diameter OTwice the diameter O Half the radius The radius...
#2 Torsion clock Design a torsion clock made of steel (shear modulus 79.3 GPa, density 7.9 g/cm3) based on a torsion wire (length 0.2 m, diameter 0.3 mm), a rod (diameter 3 mm, length 20 cm) and two small masses (20 g each) attached to the rod. Position the masses on the rod such that the resulting oscillation time is 1 s! What is the track velocity of the masses at the zero transition. if the starting amplitude is 45°,...
1) Explain, with examples, the difference between equilibrium and compatibility torsion.
Single Cell Torsion (and a little buckling) 2. (20 pts) Suppose we wish to design a minimum weight shaft of Im length to support a limit Torque of 35 kN-m. The material is specified as aluminum 6061-T6 with yield strength of 240 MPa, Young's Modulus 70.0 GPa and Poisson Ratio 0.33. We recognize that for this pure torsion application a thin-walled, hollow circular shaft is the optimum configuration, but what radius and wall thickness will minimize the weight? Determine the...
Derive the torsion formula τ=Tp/J for a circular section by assuming the section is composed of a series of concentric thin circular tubes. Assume that the shearing stress at any point is proportional to its radial distance.
Write the Hamiltonian for the 2 and H molecules and explain/label each term. What terms differ between these two systems?
