a rectangular bar of length l has a slot in the middle half of its length. the bar has width b, thickness t, and modulus of elasticity E. the slot has a width b/4. the stress in the middle region is 24000 psi, the length is 30 in, andthe modulus of elasticity is 30X10^6 psi. assume elongation max = 0.02 in.
if the total elongation of the bar is limited to 0.02 in what is the max length of the slotted region? assume axial stress in the middle region remains at 160 MPa
Describe a dynamic programming algorithm to find an independent set of T such that the sum of numbers of nodes in the set is the largest among all possible independent sets of T.
A concentrated downward force of 2000 lb. is located 6' from the left support, and a uniformly distributed load of 200 lbs./lin. ft. begins 6' to the right end of the member. What force must be applied at each connection to maintain equilibrium?
The velocity along a pathline is given by V (m/s) = s^2 x t^(1/2) where s is in meters and t is in seconds. The radius of curvature is 0.5 m. Evaluate the acceleration along and normal to the path at s = 2m and t = 0.5 seconds.
