Please solve each question with clear step-wise presentation, and in Q1 please follow the hint instructions. Thanks in advance.
The unextendable 2-ft rod AB and a spring AC of spring constant k at its unstretched length Lo are connected at A, which is originally at the horizontal position. A vertical load P is applied at A and A moves down to A* to the equilibrium position with the angles of e and a. Assume that the internal forces in the rod and the spring are denoted by Trod and Tsprin. Take
Q1: Find the internal forces Trod and Tspring (Hint: Consider the equilibrium of point A*. Follow the 3-step procedure of drawing FBD, listing equations, and finding the solution)
Q2: Find the extension of the spring.
Q3: Find the spring constant k.
A piece of lucite (transparent plastic) has an index of refraction of 1.45. Find the critical angle (for total internal reflection) if the plastic is in air. Now find the critical angle if the plastic is immersed in water. In both cases, we are co..

A worker drags a box along a frictionless horizontal floor by pulling on a rope attached to the box. The position of the box is given by x(t) = (1.500 m) + (3.650 m/s)t ? (0.300 m/s 2 )t 2 + (0.089 m/s 3 )t 3 . The box has a mass of 50.00 kg.
A 50g marble moving at 2.2m/s strikes a 30g marble at rest. Assume the collision is perfectly elastic and the marbles collide head-on. What is the speed of the first marble
The drag on ball A in fluid Y (extremely expensive and rare) is to be estimated from tests run on ball B in air (fairly inexpensive fluid). Ball A has a diameter of 1 ft and we want to drag it during fluid Y at 80degreeF at 10 ft/s. Ball B has a diam..
