Question 23 Methods for determining the metabolic demands on the job are--pick all that apply: Strain Index Bernard Marco Table lookup RULA Laboratory Direct Reading Garg's Equations ACGIH HAL Macro Look-up--pictures Bernard Predictive Method Question 24 In general, which is not true? Outward movement is less precise than inward movement Precision of hand movement is increased if the objective of the movement is 60 degrees diagonally forward Shoulder abduction will not reduce performance if the shoulders are held between 18 and 23 degrees Forearm movement is more precise than shoulder movement All the above are true Question 25 Accommodation is: Ability to bring an object into sharp focus Affected by the age of the individual Affected by the lighting conditions All the above None of the above Question 26 When designing controls for their effective operation, which is true: None are true Auditory controls are used for messages that are continually repeated O Visual displays are best used when the message is urgent and the operator moves about his workstation Controls operate as expected (they follow population stereotypes) D Question 28 1 pts Vibration, cold, and poor fitting gloves on the hand can lead to upper extremity cumulative trauma disorders because they: o Decrease required grip force All lead to a vascular response resulting in decreased blood flow to the extremities O Increase required grip force All of the above Question 29 1 pts In order for environmental factors to affect job performance, they must occur at levels at which there are serious health affect. True False Question 30 1 pts When designing workstations, it is best to: Design for the average height worker Design for the tallest worker Design for the shortest worker Design based on the type of activity the worker is required to do and the population being accommodate HI - Question 31 For an ergonomic evaluation, ergonomic effort is impacted by: The amount of physical effort applied to either muscles, tendons, or joints The distance the load is held away from the body O The size of the load held in the hands The at the weight of the load O None of the above All the above Question 32 If a patient is diagnosed as having an injury related to ergonomic risk factors, the medical commu should write restrictions that consider only: Limiting the weight of the load Limiting the number of times the patient can lift the load The posture the operator has to work in The physical work capacity of the operator All of the above Question 33 Biomechanical loads on the low back are best measured by: Evaluating the only load weight and the back angle O Measuring torque due to body weight and torque due to the load Measuring the worker height and the load size Measuring the distance the load is away from a person shoulders O Evaluating the persons age, body weight, load weight and frequency of lifting Question 23 Methods for determining the metabolic demands on the job are--pick all that apply: Strain Index Bernard Marco Table lookup RULA Laboratory Direct Reading Garg's Equations ACGIH HAL Macro Look-up--pictures Bernard Predictive Method Question 24 In general, which is not true?
