Question
Chapter 16, Problem 16.18P
Interpretation Introduction
Interpretation:
The terms decomposition temperature, heat distortion temperature, glass-transition temperature and melting temperature are to be defined. Also, the reason for the thermoplastics to not have fixed melting or glass-transition temperature is to be explained.
Concept Introduction:
Polymers are the large molecules which are made up of many small repeating units bonded together in linear, branched or cross-linked manner.
They are of two types: natural and synthetic. Natural polymers are those which occur naturally, and synthetic polymers are those which are synthesized or man-made.

PROBLEM 15.236
The arm AB of length 16 ft is used to provide an elevated
platform for construction workers. In the position shown, arm
AB is being raised at the constant rate de/dt = 0.25 rad/s;
simultaneously, the unit is being rotated about the Y axis at the
constant rate ₁ =0.15 rad/s. Knowing that 20°, determine
the velocity and acceleration of Point B.
