The average specific heat of the human body is 3.6 kJ/kg · °C. If the body temperature of an 80-kg man rises from 37°C to 39°C during strenuous exercise, determine the increase in the thermal energy of the body as a result of this rise in body temperature.
Cork is used for sealing sparkling wine bottles. Aside from friction, why not use rubberbto seal wine bottles. (Hint: think about the force exerted by the pressure inside and how does that deform each material) Be sure to use poissons ratio in the..
The force exerted by the potatoes on the frame at one side of the chair is equivalent to horizontal and vertical forces of 24 N and 84 N, respectively, at E and a force of 28 N perpendicular to member BH at G.
A contractor has both a 3-cy and a 5-cy shovel in the equipment fleet. Select the minimum-size shovel that will excavate 400,000 bcy of common earth in a minimum of 130 working days of 8 hr each.
A soil, 150mm x 150mm x 20mm high, is subjected to simple shear deformation. The normal force in the Z direction is 1 kN and the shear force is 0.5 kN. The displacements at the top of the soil in the X and Y directions are delta x = 1mm and delta z =..
