For the problems below, read Appendix F and then download and use MIL-HDBK-5J to com- plete. References to pages or sections of MIL-HDBK-5J begin with the text MH. All problems are for materials at room temperature unless otherwise noted.
1. A1 Consider a specimen that is 12 in. long * 1.50 in. wide that is cut from a sheet of 0.0625 in. thick 17-7PH stainless steel in the TH1050 aging condition. Properties for this material are described in Section MH2.6.10. The load is applied in the 12 in. direction, this corresponds to the L direction for the sheet.
(a) PH in the material designation means "precipitation hardened." Review the information on page MH2-213 and state the heat treatment steps for the material to be in the TH1050 condition.
(b) What is the tensile load (in lb) required for the specimen to reach the B basis yield stress?
(c) What is the length of the specimen under the load in part (b)?
A 40-N crate starting at rest slides down a rough 6.0-M long ramp, inclined at 25 degrees with the horizontal. 30J of energy is lost to friction. What will be the speed of the crate at the bottom of the incline?
Ball A is dropped from the top of a building of height H at the same instant ball B is thrown vertically upward from the ground. First consider the situation where the balls are moving in opposite directions when the collide.
A converging lens with a focal length of +18.0 centimeter is placed 12 centimeter to the left of a diverging lens having a focal length of -13 centimeter. Find where is the image placed as measured from the diverging lens
A box is put on a slide to move it from one part of a factory to another the slide is at an angle of 20 degrees below the horizontal the coefficient of friction between the box and slide is 0.352 what is the acceleration of the box.
q1. two small charged metal spheres a and b are situated in a vacuum. the distance between the centres of the spheres
A projectile of mass 2.0 kg approaches a stationary target body at 5.0 m/s. The projectile is deflected through an angle of 59.5° and its speed after the collision is 2.8 m/s. What is the magnitude of the momentum of the target body after the collisi..
Is kinetic energy consumed in the third type of collision studies? Classify the three collision kinds as elastic, inelastic, or completely inelastic.
What is the best estimate of the uncertainty in any single one of the distance measurements?
If a force of 2 Newton is needed to open a 92 centimeter wide door when applied at the edge opposite the hinges, determine what force must be applied to open the door
What will most likely cause arcing at the switch contacts.
The force component along the displacement varies with the magnitude of the displacement, as shown in the graph. Find the work done by the force in the interval from 0 to 0.1 m
