Asolid square rod is cantilevered at one end. the rod is 0.6 m long and supports a completely reversing transverse load at the other end of 62 kn. the material is aisi 1080 hot-rolled steel. if the rod must support this load for 104 cycles with a design factor of 1.5, what dimension should the square cross section have?

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
