Q4. (5-108) A 68-kg man whose average body temperature is 39°C drinks 1 L of cold water at 3°C in an effort to cool down. Taking the average specific heat of the human body to be 3.6 kJ/kg-°C, determine the drop in the average body temperature of this person under the influence of this cold water.

1.) A.) A cutting operation is performed on a piece of metal. The rake angle of the tool, α, is eight degrees. The tool penetrates the work to a depth of 8mm. The chips generated from this cut are 20mm thick. Calculate the shear plane angle, Φ, in the orthogonal model for this operation. Give your answer in degrees B.) For the same cutting operation, the cutting and thrust forces are measured. The cutting force is measured as 1600N, and the thrust force is measured as 1300N. The width of the cut is 4mm. What is the shear stress applied by the tool? Give your answer in MPa.

In the gear train shown gear 3 is carried on arm 5, Gear 3 meshes with gear 2 and gear 4. The number of teeth on gear 2, 3 and 4 are 60, 20, and 100, respectively. If gear 2 is fixed and gear 4 rotates with an angular velocity of 100 rpm in the counterclockwise direction, the angular speed of arm 5 (in rpm) is 4 2 3 5

The vertical distance above a reference datum to a point is called the point’s
