11.24 A swivel C bracket shown in Figure P11-24 is mounted to a ceiling of a building and has a speaker (not shown) of 30 lbf hanging from each mounting hole. The mounting bracket is made of A 36 steel with a modulus of elasticity of 29 \times 10$^6$ psi, Poisson's ratio of 0.29, and yield strength of 36,000 psi. Determine the maximum von Mises stress and deflection in the bracket. (This problem is by Tyler Austin and Kyle Jones)

Electrical synaptic transmission from the lateral giant axon (LGN) to the giant motor axon in crayfish is strongly unidirectional... entirely because of the rectification of gap junctions at the synapse. because of the rectification of the gap junctions at the synapse, AND the HIGHER input resistance of the post-synaptic giant motor axon compared to the presynaptic axon. because of the rectification of the gap junctions at the synapse, AND the LOWER input resistance of the post-synaptic giant motor axon compared to the presynaptic axon. entirely because of the relatively LOW input resistance of the post-synaptic giant motor axon. entirely because of the relatively HIGH input resistance of the post-synaptic giant motor axon.

a. Sketch a wye-connected three-phase power source feeding a balanced three-phase wye-connected resistive load. Include the neutral line. b. Assuming a 120VAC, 60Hz source and a 600\Omega load per phase, calculate the phasor values of the phase voltages and currents and the neutral current. Use the phase a source voltage as the reference (zero) angle.
