What rule is used in fixed exposure technique systems?

Examples of artifacts that must be accepted include all of the following except1. pacemakers.2. dental bridges.3. pleural drainage tubes secured with safety pins.4. endotracheal tubes.5. heart monitoring lines.

Given the image of a box on an incline shown in Question 21, If the static friction coefficient between the box and the slope is 0.5, what magnitude of horizontal force is required to push the box up the slope?  Provide your answer in kN, but do not include units in your submittal.

Essential characteristics of a PACS include:1. distribution and retrieval of digital images2. creation of digital images3. radiation dosage documentation4. display of digital images5. voice-activated dictation6. digital image storage and long-term archival

Given the image of a box on an incline shown in Question 21, If the static friction coefficient between the box and the slope is 0.2, what magnitude of horizontal force is required to prevent the box from sliding down the slope?  Provide your answer in kN, but do not include units in your submittal.

The differences between CR and DR include 1. CR uses IPs 2. CR has higher DQE and lower patient dose 3. CR images are displayed immediately

The box is at rest, but about to slide down the slope.  What is the static friction coefficient?  

Given the beam in Question 14, select the best choice for internal moment equation.

Given the beam shown in Question 7, which choice best describes the direction of internal moment at node B?  

Given the beam shown in Question 7, determine the absolute magnitude of internal moment at node B.  Provide your answer in kN m, but do not include units in your submittal.
