Which has a greater momentum, a heavy truck at rest or a moving skateboard?
Ans. The skate board. Momentum = mass x velocity. Since the truck is not moving, it has

(Work Energy Theorem) A child applies a force F parallel to the x-axis to a sled of mass m moving
on the surface of a frozen pond. As the child controls the speed of the sled, the x-component of
the force she applies varies with the x-coordinate of the

Work-Energy Theorem) A watermelon of mass m is dropped from rest from the roof of a building
of height h and feels no air resistance.

Example 3.1 Calculate and check the design strength of the connection shown below. Is the
connection adequate for carrying the factored load of 60 kips? Assume A325 bolts.
Solution
Step I. Shear strength of bolts
The design shear strength of one bolt in s
1. Consider a lottery with three possible outcomes: $100 will be received with
probability .1, $50 with probability .2, and $10 with probability .7.

What is the expected value of the lottery?
The expected value, EV, of the lottery is equal to the sum o

3.2 BOLTED SHEAR CONNECTIONS
We want to design the bolted shear connections so that the factored design strength (Rn) is
greater than or equal to the factored load.
So, we need to examine the various possible failure modes and calculate the corresponding
3.1 INTRODUCTORY CONCEPTS
There are different types of bolted connections. They can be categorized based on the type of
loading.
Tension member connection and splice. It subjects the bolts to forces that tend to shear
