Use that to determine the nozzle reactive force (See figure 1). • Force is a push or a pull that induces motion, changes state of motion, or stops a moving body when applied. This formula is used to calculate the force required to clamp the mold halves during injection molding. Area estimation When the mold is not fully designed, we only know the projected area a3 of the product, and estimate it. Pressure is the force applied by one object on the another. The amount of pressure required from other EXAIR products can be determined, i.e. Contact Area (A) The basic formula for pressure is F/A (Force per unit area). 2. The force, applied on a unit area of a surface is known as pressure (Pressure = force/area on which it acts). Answer (1 of 4): Before you worry about where the 'formula' comes from, first ask yourself what is meant by pressure. The equation for working out pressure is: pressure = force ÷ area. answer choices. We denote this direction by the letter n. a = acceleration. this is the reason that the area of one end of a nail is pointed (to exert sufficient pressure) and other end is bigger (as shown in the image given below). It can be expressed in pounds, tons, grams or kilograms. The hydrostatic pressure at depth h is due to the pressure exerted by the fluid above it. EFFECTIVE STRESS AND SEEPAGE PRESSURE No flow condition, 42. Pressure is defined as the force divided by the area perpendicular to the force over which the force is applied, or. This means that the more pressure or the larger an actuator, the more force you have. The Force required to assemble (press fit) cylindrical parts depends on the allowance or clearance between the cylindrical parts for the fit, area of the positioned and fitted surfaces, the pressure increasing in proportion to the distance that the shaft feature is forced in. 1 ] A water glass sitting on a table weighs 4 N.
