Four bar chain is given with length of links as follow: Link 1 = 74mm, link 2 = 96 mm, link 3 = 60 mm, Link 4 = 70mm. Determine: a) Whether it belong to class 1 or class 2 category of mechanisms. b) Describe all possible inversions with explanations


Programming Tasks: Apply all the things you have learned in this module. All program


should detect events like click on the buttons and keypress to detect inputs.


Task 1: Design and develop a program that will accept inputs like Name, Course and


Year Level. These inputs will be displayed in a message box after a button is clicked.


Task 2: Design and develop a program that will compute the take home amount for the


loanable amount of the customer. For example, if the customer’s loanable amount is


100,000.00 and has a 3% per annum interest. The company will deduct the interest for 5


years which is (15,000.00) to the loanable amount, so, the take home amount of the


customer is 85,000.00. Your program allows the user to input loanable amount and how


many years for the customer to pay the loan. Set the interest per annum to 3%.

A cube of mass 10 kg is at rest on a horizontal surface when it is subjected to a horizontal force P that varies with time t as P = 20t. If the static and kinetic coefficients of friction are both 0.4, calculate the velocity of the cube after 5 s.


Create a class named Square which performs the following tasks. a. Provide a method which returns calcuated area and circumference of the square and takes side length as one parameter of type integer. Write a test application named SquareApp which performs the following tasks. a. Create an object for the class Square. b. Read the side length of the Square from the user c. Pass the side length to the methods of the square class as an argument and print the calculated area and circumference of the square.


Programming Tasks:

1. Write a program that will determine if one or both textboxes for username and

password contains empty string. If username or/and password is/are empty then it will

display a message that username and password is required. Otherwise, it will determine

if it correct or incorrect.

2. Write a program implementing Select Case statement that evaluates a character either a

vowel or a consonant.

3. Write a program implementing While loop statement, any Do loops statement, any For

loops statement that display your Name, School, Course and Year level 10 times with

the use of message box.


A 10Mg truck rolling at a constant speed of 30 kph along a horizontal rail comes to an incline of slope sin 0.1. Calculate how far it will coil up the slope before coming to a halt, (a) ignoring all resistive forces, and (b) assuming the rolling vesistance is 5% of the normal reaction of the truck


An aliquot of 10 mL from a 12-mol/L aqueous silver solution was transferred into a 100-mL volumetric flask and diluted with water up to the mark. A 10-mL aliquot of the diluted silver solution was transferred into another 100-mL volumetric flask and diluted with water up to the mark. What is the concentration of the final dilution?


  1. The reaction of peroxydisulfate ion (S2O2-8) with iodine ion (I-) is


S2O82-(aq)+3I-(aq)2SO42-(aq)+I3-(aq)




A stockroom clerk returns three safety helmets at random to three steel mill employees who had previous checked them. If Gary, Yuri and Cris, in that order, receive one of the three hats, list all the sample points for the possible orders of returning the helmets, and find the values of random variable X representing the number of correct matches. *
