MID-TERM TEST 01

Time: 60 minutes

I Reading comprehension: (10 points)

Read the passage below and then answer the questions.

Beams are structural members whose primary purpose is to carry transverse loads Most beams carry some rather small loads in their axial direction (or perhaps tensional loads) along with transverse load during

their service, but these loads and especially their effects on the beam, are usually small in comparison with the

transverse loads The beams we are mainly concerned with here are relatively slender members assumed stable against lateral buckling The loads considered are resolved into components parallel and perpendicular (transverse) to the longitudinal axis of the beam Only the transverse component and their effects will be considered at this time

It is perhaps advisable at this time to clearly classify the types of beams and the type of reactions before

we proceed to investigate the shear forces and moments Beams are divided into two groups, statically determinate and statically indeterminate When the reactions can be obtained from the equations of equilibrium alone, the structure is statically determinate When the equations of equilibrium are not sufficient to determine the unknown reactions, the structure is said to be statically indeterminate

1 What is the definition of beams in this passage?

2 What does “these loads” in line 3 refer to?

3 Compared to transverse loads, are the tensional loads mentioned in the passage smaller or larger?

4 How many groups do beams comprise? What are they?

5 In which case is the structure called statically indeterminate?
