Discuss some of the circumstances where mechanical ventilation is required in the welding standards. Do you believe this requirement is reasonable? Why, or why not?
Discuss some of the problems that might be encountered when implementing OSHA's machine guarding standards in the workplace. Do you feel that the standards are adequate to control machine guarding hazards in general industry? Why, or why not?
The problems that exist when implementing OSHA's machine safeguards are associated with the actual safeguarding standards themselves. Because of the complex automation systems ...
Solution Summary
The general mechanical ventilation system are analyzed. The solution determines if the standards are adequate to control machine guarding hazards in general industry. The circumstances where mechanical ventilation is required in the welding standards are determined.

Consider two satellites, A and B, both of mass m, moving in the same circular orbit of radius r around the Earth, of mass Me, but in opposite senses of rotation and therefore on a collision course.
a) In terms of G, Me, m, and r, find the total mechanical energy Ea and Eb of the two satellites plus Earth's system before col
A laboratory has four hoods each of which is 39 inches wide. When the hood door is open to a height of 8 inches and the hoods are operating, the average air velocity through the hood is 170ft/min.
a. Evaluate the total ventilation rate for this room assuming that there are no other exhausts.
b. The laboratory is designed for
An atrium has a floor area of 30 m by 20 m and is 20 m high. The ceiling ventilation is designed for a fuel area of 30 m2 with an energy release rate of 0.5 MW/m2. The inlet openings are very large. An effective heat conduction coefficient can be assumed to be 20 W/m2°C.
(a) Calculate the area of ceiling vents required for e
As a result of a chemical spill, benzene is evaporating at the rate of 1 gram per minute into a room that is 6 m * 6 m * 3 m in size and has a ventilation of 10 m3/min.
a- Compute the steady state concentration of benzene in the room.
b- Assuming the air in the room is initially free of benzene, compute the time necessary fo
A block of mass M slides along a horizontal table with speed Vo. At x=0 it hits a spring constant k and begins to experience a frictional force. The coefficient of friction is a variable and is given by u=bx, where b is a constant. Find the loss in mechanical energy when the block has come momentarily to rest.
I am having trouble with the type of question listed below and any help would be greatly appreciated. I have attached a diagram also.
A block P of mass m is attached to three springs whose other ends are attached to fixed points A, B and C. I have listed the stiffnesses of the three springs and their natural lengths below. Th
The study is to find out if the analysis of the data supports a smoking ban or not. I have conducted a Mann Whitney, and N-Par test and discovered that the data is skewed. I need to explain what the results mean in a discussion section, and am unsure because the data is a little random. Can you help?
