A steel cable supports a lift that can carry a maximum load of 1600Kg and it moves with an acceleration (a). (Young modulus of steel (Y)=3x1011 N/m2. Proportional limit stress =2x1010N/m2). Determine whether the maximum tension in the cable occurs as the lift is ascending or descending. And if this maximum tensile force is 25 KN, determine the value of the acceleration (a)?

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

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
