What kind of power does the Curiosity rover use?
The rover’s power comes from a multi-mission radioisotope thermoelectric generator, which produces electricity from the heat of plutonium-238’s radioactive decay. According to NASA, Curiosity has four main science goals in support of the agency’s Mars exploration program: Determine whether life ever arose on Mars. Characterize the climate of Mars.
What should the torque be for torquing bolts?
Torquing –Tightening flanged joints in which torsional loads are applied to the bolts causing the bolt to stretch, due to the relative movement between the nut threads. Ordinarily, the torque applied should not be outside of the 40-60% of minimum yield range.
What are the torque values for lock nuts?
IFI-100 does not govern lock nuts above 1″. The values shown in the chart are to be used as a mid- range guideline. ** Torque values for 1/4″ and 5/16″ sizes are in inch lb. All other torque values are in foot lb. Grade C Grade B Grade G Phone: 1-800-558-2808 • Fax: 1-800-553-8769 • www.imperialsupplies.com A56 BOLT CLAMP LOADS
Which is the best way to control torque?
Control bolt hardness, finish, and geometry. Use “soft” bolts and tighten well past yield point. Use consistent snugging torque. Control bolt hardness and dimensons. Use bolts with flat, parallel ends. Leave transducer engaged during tightening operation. Mount transducer on bolt centerline.
What’s the best way to determine a torque specification?
There are two ways to come up with a torque specification: “The right way and the wrong way,” quips David Archer, principal engineer at Peak Innovations Engineering, a consulting firm specializing in bolted joint design and analysis.
