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.

Sasha has just gotten a new job in a nearby city. after comparison shopping, she found that renting a nice two-bedroom apartment would cost around $800 per month. her utilities would cost about $150 per month. sasha has enough money saved for a down payment, and she found that she can buy a three-bedroom house or condo with a mortgage payment of $1,000 per month, including taxes and homeowner's insurance. her utilities would cost about $200 per month. what is the advantage of buying the house over renting the apartment?
