Chapter 1: Problem 4

Search online at http://www.osha.gov and from 29 CFR \(1910.211\) Definitions, define the following power press terms: brake, clutch, two-hand control device, die, foot pedal, pinch point, point of operation. Regulations for power presses are presented in 29 CFR 1910.217. Show a power press and identify the location of each item.

Short Answer

Expert verified
The definitions are as follows: Brake is the component to stop and control. Clutch engages and disengages the power transmission. Two-hand control device ensures operator's hands safety. Die shapes or cuts the material. Foot pedal controls the machine using foot. Pinch Point is where injury can occur between moving and stationary parts. Point of operation is where work is performed on the material.

Step by step solution

01

Visit the website

Go to the website http://www.osha.gov and navigate to the 29 CFR \(1910.211\) Definitions page.
02

Define Brake

Brake is the component of the power press that stops and controls the motion of the machinery.
03

Define Clutch

A clutch is a device that engages and disengages the power transmission, especially from the driving shaft to the driven shaft. In a power press, the clutch is what allows the operation to begin.
04

Define Two-Hand Control Device

Two-hand control device requires concurrent use of both hands to trip the machine. It protects the operator's hands by ensuring they are not on the danger area when the machine cycles.
05

Define Die

In a power press, the die is the tool that gives the material its shape. It's used in conjunction with the press to shape or cut material.
06

Define Foot Pedal

Foot pedal in press operates similar to a two-hand control device but is pedal operated. This type of control is engaged using the foot, it is used to either start, stop or control the speed of the machine.
07

Define Pinch Point

A pinch point is any point at which it is possible for a person or part of a person's body to be caught between moving parts of a machine, or between the moving and stationary parts of a machine.
08

Define Point of Operation

Point of Operation is the area on a machine where work is actually performed upon the material.
09

Show a power press and identify each item

Refer to a diagram of a power press. Identify and mark the brake, clutch, two-hand control device, die, foot pedal, pinch point, and point of operation on the diagram.

Develop an equation for the power required, in hp, for a vehicle traveling on a level road to overcome (a) the aerodynamic drag force of the surrounding air on the vehicle and (b) the rolling resistance force on the tires. The drag force, \(F_{d}\), imposed on a vehicle by the surrounding air is given by $$ F_{d}=C_{d} A \frac{1}{2} \rho V^{2} $$ where \(C_{d}\) is a constant for the vehicle called the drag coefficient, \(A\) is the projected frontal area of the vehicle, \(\rho\) is the air density, and \(V\) is the velocity of the vehicle. The rolling resistance of the tires, \(F_{r}\), opposing the motion of a vehicle is given by $$ F_{r}=f W $$ where \(f\) is a constant called the rolling resistance coefficient and \(W\) is the vehicle weight. What is the equation for the power required in \(\mathrm{kW}\) ?

Describe the BP oil spill disaster and answer the following questions: (1) When did the oil spill occur? (2) How much oil was spilled in the Gulf of Mexico? (3) What was the "cost" of the oil spill? (4) What role did engineering play in this spill from a safety, ecological, and sociological standpoint? Your write-up should reflect the professional appearance expected of an engineer.

Search online at http://www.osha.gov and print a copy of \(29 \mathrm{CFR} \mathrm{} 1910.212\), General requirements for all machines. With these requirements in mind, identify a machine you have used that had a machine guard to protect the operator or other person in the machine area from hazards. Sketch the machine and label the guarding device, power source, point of operation, and danger zone.

Parking blocks prevent the forward movement of cars and other vehicles by acting like a "curb." Unfortunately, for elderly persons or others with poor vision, they are sometimes difficult to "see" as they project only four to eight inches off the ground. An ASTM standard recommends that parking blocks not be used in parking lots and parking garages. On the other hand, the Americans for Disabilities Act (ADA) shows the use of parking blocks in the design of parking spaces for persons with disabilities. What are the advantages and disadvantages of parking blocks? What is your opinion as to whether the utility outweighs the risk of harm of using parking blocks? Are there certain places where parking blocks should not be used? Are there parking garages that do not use parking blocks?

A press delivers a force of \(8000 \mathrm{~N}\) throughout a distance of \(18 \mathrm{~mm}\) each stroke. Select a number of strokes per minute and determine the rate of work output per second. If the press efficiency is \(90 \%\), what average torque must be provided by a 1750 -rpm driving motor?
