Go!When calculating directional forces, 'g' is expressed as:
The acceleration due to gravity, 9.823 m/sec2 (32.2 ft/sec2). For cargo securement purposes it is expressed as a percentage of cargo weight, i.e. .5g is 50% of force of gravity or 50% of cargo weight.
Which of the following is not a requirement of wood used as blocking or bracing?
If wood is used:
As part of their pre-trip cargo securement inspection, drivers should:
When securing concrete bell pipe in multiple complete tiers, all of the following are true except:

Bells of the upper tiers must be are on the opposite side of the vehicle from the bells of the tier below.
The load carrying area of a truck, trailer, or intermodal container is referred to as the:
The load carrying area of a truck, trailer, or intermodal container.
To secure a cubic-shaped boulder, how many tiedowns are required, at minimum?
The securement of a cubic-shaped boulder must meet these requirements in addition to the other large boulder requirements in Section 13.
Secure each boulder individually with at least two chain tiedowns placed side-to-side across the vehicle.
Place tiedowns as closely as possible to the hardwood blocking used to support the boulder.
What types of freight need to be secured properly?
Aggregate Working Load Limit is defined as:
The summation of the working load limits or restraining capacity of all devices used to secure an article on a vehicle.
When securing paper rolls with eyes crosswise, which of the following can be used to prevent side-to-side shifting when there is more than 8 inches of space to the wall?
If there is more than a total of 203 mm (8 in) of space between the ends of a paper roll and other rolls or the walls of the vehicle, use one of these methods:
When securing paper rolls with eyes horizontal, which of the following should be used to secure the rear-most roll?
Note: Chocks, Wedges, or Blocking Securing the Front or Rear Roll - Hold in place by some means in addition to friction so they cannot become unintentionally unfastened or loose while the vehicle is in transit. This is often accomplished with nails.
Do not secure the rearmost roll with:
Studying the flatbed cargo securement CDL manual is not a requirement for getting your CDL permit or license. It is required knowledge for flatbed drivers.
Some questions you should be able to answer for flatbed cargo securement:
Any device specifically manufactured to attach or secure cargo to a vehicle or trailer:
A combination of securing devices that forms an assembly that:
Some tiedowns are attached to the cargo and provide direct resistance to restrain the cargo from movement.
Some tie-downs pass over or through the cargo. They create a downward force that increases the effect of friction between the cargo and the deck. This friction restrains the cargo.
A combination of securing devices which form an assembly that attaches cargo to, or restrains cargo on, a vehicle or trailer, and is attached to anchor point(s).
Cargo is contained if it fills a sided vehicle, and every article is in contact with or sufficiently close to a wall or other articles so that it cannot shift or tip if those other articles are also unable to shift or tip.
A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
Tiedowns can be used in two ways:
Place the tiedown as close as possible to the spacer.
Position the tiedowns as symetrically as possible over the length of the article.
Position the tiedowns to preserve the integrity of the article.
