Determine the minimum force capacity press to perform the blanking and punching operation in Problem 19.3 under the following conditions: (a) blanking and punching occur simultaneously and (b) the punches are staggered so that punching occurs first, then blanking. The aluminum sheet metal has a tensile strength

the closer the planet is to the sun, the larger the gravity

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
