Search online at https://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. From your viewpoint, address the issue of whether the latching system on the incident squat machine created an unreasonable danger. (Alternatively, address the question as to whether a specific hack squat machine is a "reasonably safe design" and whether a safer alternative design exists.)
a vessel contains 2 litres of gas at a pressure of 300 kpa and a temperature of 27degc. 3 litres of gas at the same
A structure built in at point O supports 70 and 85 N couples and a tip moment. Determine the resultant couple moment, using both scalar and vector approaches.
Give a complete design analysis of a single plate clutch, with both sides effective of a vehicle to transmit 22 kW at a speed of 2800 r.p.m. allowing for 25% overload. The pressure intensity is not to exceed 0.08 N/mm^2 and the surface speed at the m..
A rigid tank initially contains 3 kg of saturated water vapor at 140°C. Heat transfer occurs, and the pressure drops to 200 kPa. Assume that kinetic and potential energies are negligible. Determine the amount of energy transfer by heat, in kJ.
In a heating/humidifying system moist air first flows through a heating coil and then through an air washer. The air enters the system at 55 °F dry-bulb temperature and 40 % relative humidity. The air exits the system at 90 °F dry-bulb temperature an..
Research on the following three aspects via patents, journals, reports, online resources, etc- Design and Theory and Fabrication.
steam enters a two-stage adiabatic turbine at 8 mpa and 550ordmc state 1 and is expanded to 2 mpa state 2 in the first
Explain the basic operating principles of each product and compare the advantages and disadvantages of each. Consider sensitivity, accuracy, calibration, and cost.
Determine the horizontal displacement of nodes D and E and compare the magnitude with the vertical displacements found in .
Two kilograms of water undergo a process from an initial state where the pressure is 2.5 MPa and the temperature is 400°C to a final state of 2.5 MPa, 100° C. Determine the entropy change of the water, in kJ/K, assuming the process is irreversibl..
Laboratory measurements of water flowing across a flat plate indicate a local shear stress of 2.3 Pa. the free-stream velocity of the water is 5 m/s. If the free-stream & plate temperature are 15 C & 60 C, respectively, what is the local heat flux?
a particle is moving along a curved path that is defined by xy2 100 where x and y are positive and measured in inches.
