Mechanical Properties of Solids

There are three types of matter- solid, liquid and gas. Out of them, solids have a rigid shaped and size. The intermolecular forces of attractions in solids are greatest. Mechanical properties are the physical properties of a material which it shows, when it is provided with certain amount of force or load. These properties are to be kept in mind for various purposes. When a force is applied to an object, the object may or may not get deformed depending upon its elastic property. But every time the object develops a restoring force against the force applied. This is commonly known as stress. If the object changes its dimensions due to the force applied it develops strain ( which is the ratio of change in dimension to the original dimension).

Question

Fp
For the glenohumeral joint shown above, there are two muscle
force: F, (deltoid) and Fs (supraspinatus) with values as follows:
Fp = 400 N acting at an angle of 10 degrees with respect to
vertical
Fs= 200 N acting at an angle of 25 degrees with respect to
horizontal
a) By adding these force vectors, solve for the net force acting
on the glenohumeral joint (magnitude). The opposite of this net
force is referred to as the joint reaction force.
b) What is the predominant orientation of this joint reaction
force (ie, superior, inferior, medial, lateral, anterior or
posterior)?
c) What shoulder muscle might be able to counterbalance this
force? Your text from your A&P course will be helpful here.
