Loads P = 500 N and Q = 795 N act on an oak beam. Determine the magnitude of the largest shear force (consider both positive and negative values) in the beam. Let a = 0.7 m and b = 1.9 m.

A nurse is caring for a patient who is being treated for Covid-19 pneumonia and ARDS and requires a mechanical ventilator. The physician orders an arterial blood gas, which provides the following results: pH = 7.18, pCO2= 48 mmHg, HCO3= 29 mEq/L, SaO2=92%. Based on these results, which of the following best describes this patient’s condition?

A patient previously diagnosed with a pulmonary embolism was on a weight-based heparin protocol at 12 units/kg/hour. His aPTT was drawn at 1800 and was 35 seconds.  Per the heparin order, you will need to increased the heparin by 2 units/kg/hour. What will be the new infusion rate? The patient weighs 157 pounds. (round to the nearest whole number)

Which if the following statement is true about the problem of heterogeneous preferences in public goods?

 If lucky people earn Ylucky=100 and unlucky people earn Yunlucky=50 with a 50/50 chance symmetrical luck component μ, s.t.μlucky= -μunlucky what is the value of μ?

Six toy blocks are glued together to form a beam that supports a shear force of 149 N. Each block has dimensions a = 13 mm and b = 39 mm. Determine the maximum horizontal shear stress in the beam.

A cylindrical beam supports a shear force of 12.7 kN. The outside diameter is 74 mm, and the wall thickness is 4 mm. Determine the maximum horizontal shear stress in the beam.

Six toy blocks are glued together to form a beam that supports a shear force of 202 N. Each block has dimensions a = 15 mm and b = 45 mm. Determine the horizontal shear stress in the glue between blocks (2) and (3).

Three toy blocks are glued together to form a beam that supports a vertical shear force of 109 N. Each block has dimensions a = 8 mm and b = 24 mm. Determine the horizontal shear stress in the glue between blocks (1) and (2). The moment of inertia around the horizontal centroidal axis of the beam is 109,568 mm4.

A 172-lb person stands on an oak beam. Determine the vertical reaction force at the right end of the beam. Let a = 84 in. and b = 24 in.
