A basketball with an inside diameter of 8.54 in. and wall thickness of 0.051 in. is constructed from a polymer that has a yield strength of 3.09 ksi. If the ball is inflated to a pressure of 7.0 psi, determine the factor of safety with respect to the yield strength.

An aluminum CO2 [E = 10,000 ksi; ν = 0.33] bottle has an outside diameter of 3.28 in., a wall thickness of 0.160 in., and a yield strength of 59.0 ksi. If a factor of safety of 2.9 is required, determine the maximum pressure that the bottle may contain.

A Pop-A-Shot ball with an inside diameter of 6.52 in. and wall thickness of 0.042 in. is constructed from a polymer that has a yield strength of 3.29 ksi. If the ball is inflated to a pressure of 4.3 psi, determine the factor of safety with respect to the yield strength.

A basketball with an inside diameter of 8.94 in. and wall thickness of 0.040 in. is constructed from a polymer that has a yield strength of 3.03 ksi. If the ball is inflated to a pressure of 7.8 psi, determine the factor of safety with respect to the yield strength.

For this vessel, the stress in the x-direction is the _______.

A 28-year-old male patient arrives at the clinic after a motorbike accident in which he sustained a deep laceration to his lateral forearm. On examination, he has lost the ability to feel fine touch and temperature sensations in part of his thumb, index, and lateral portion of the palm. He also complains of weakened grip strength. The physician suspects injury to a specific nerve and orders electromyography and nerve conduction studies. Further examination reveals that the nerve affected also provides motor innervation to some forearm flexors and muscles of the thenar eminence. Based on the location of the injury and the symptoms presented, the physician provides a diagnosis and begins treatment focused on nerve regeneration and occupational therapy. Question: Which of the following nerves is MOST likely injured in this patient?  

  Synapse Function Scenario:During a neuroscience lecture, the professor explains the part of a neuron that sends a signal across the synapse. This region is referred to as the: A. Postsynaptic terminalB. Presynaptic terminalC. Axon hillockD. Myelin sheath    

A 52-year-old patient presents to the neurology clinic with persistent headaches, nausea, and occasional visual disturbances. MRI imaging reveals a benign mass growing near the midline of the brain, just superior to the brainstem and nestled between the two halves of the thalamus. The physician explains that this mass is beginning to obstruct the normal flow of cerebrospinal fluid, leading to increased intracranial pressure. As a student observing the case, you are asked to predict which anatomical space is most likely being compressed and contributing to the patient’s symptoms.
