You are able to hold out your arm in an outstretched horizontal position because of the action of the deltoid muscle. assume the humerus bone has a mass m1=3.6kg, length l=0.66m and its center of mass is a distance l1=0.33m from the scapula. (for this problem ignore the rest of the arm.) the deltoid muscle attaches to the humerus a distance l2=0.15m from the scapula. the deltoid muscle makes an angle of ? =17? with the horizontal, as shown. (figure 1) (figure 2) use g=9.8m/s2 throughout the problem. find the tension t in the deltoid muscle. using the conditions for static equilibrium, find the magnitude of the vertical component of the force fyexerted by the scapula on the humerus (where the humerus attaches to the rest of the body).now find the magnitude of the horizontal component of the force fx exerted by the scapula on the humerus.

so here is the information for current research:

-nrel's geothermal analysts, scientists, and engineers perform a full range of research from developing advanced methods of locating and accessing geothermal resources to exploring innovative technologies to extract and produce clean energy from the heat of the earth

and here is the information for the technology of geothermal energy:

-it's clean and sustainable

-resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma

-almost everywhere, the shallow ground or upper 10 feet of the earth's surface maintains a nearly constant temperature between 50° and 60°f (10° and 16°c)

-geothermal heat pumps can tap into this resource to heat and cool buildings

-a geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building

-in the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system

-in the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger

-the heat removed from the indoor air during the summer can also be used to provide a free source of hot water
