Sample questions

1. 1.A worker is pushing a box weighing $1500 \, \mathrm{N}$ up a ramp $6.00 \, \mathrm{m}$ long onto a platform $1.50 \, \mathrm{m}$ above the ground. What is the mechanical advantage and what is the effort applied?
2. 2.A pulley system has a $VR = 5$. If the efficiency of the system is $80\%$, find its $MA$.
   • A.4
   • B.3
   • C.2
   • D.1
3. 3.In a single fixed pulley, if the load $L$ is 10 kgf, what is the effort $E$ required to lift the load in the ideal case?
4. 4.Define a machine and select the option that correctly states its four main functions.
   • A.A device that overcomes a large resistive force by applying a small force, with functions: (1) force multiplier, (2) changes point of effort, (3) changes direction of effort, (4) gains speed.
   • B.A tool that increases energy output, with functions: (1) generates power, (2) reduces friction, (3) amplifies motion, (4) converts energy forms.
   • C.A mechanism that only changes the direction of force, with functions: (1) reverses effort, (2) balances loads, (3) stabilizes motion, (4) minimizes effort.
   • D.A device that solely multiplies speed, with functions: (1) accelerates objects, (2) increases distance, (3) reduces time, (4) optimizes efficiency.
5. 5.The handle of a nutcracker is $16\mathrm{cm}$ long and a nut is placed $2\mathrm{cm}$ from its hinge. If a force of $4\mathrm{kgf}$ is applied at the end of the handle to crack it, what weight, if simply, placed on the nut will crack it?
   • A.$15\mathrm{kgf}$
   • B.$32\mathrm{kgf}$
   • C.$4\mathrm{kgf}$
   • D.$9\mathrm{kgf}$
