Q. The collar A in Figure slides along the rotating rod OB. The angular position  of the rod is given by 𝜃 =2/3 *(𝜋𝑡)² rad and the distance of the collar from O varies as r =18t⁴+4 m, where time t is measured in seconds. Determine the velocity and acceleration vectors of the collar at t =0.4 s. Solution  :-     Given polar co-ordinates are      r = 18t⁴+4       and       𝜃 =2/3 ×(𝜋𝑡)²      r`= 72t³                        𝜃` =4/3 ×(𝜋𝑡)      r``= 216t²                    𝜃`` =4/3 ×(𝜋) At t=0.4 sec       r = 18(0.4)⁴+4 = 4.46m       r`= 72(0.4)³ = 4.608 m/a       r``= 216(0.4)² = 34.56 m/s²      𝜃 = 2×(3.14×0.4)²/3 =0.335 rad      𝜃`= 4×3.14×0.4/3   = 1.675 rad/sec      𝜃``= 4×3.14/3 = 4.188 rad/sec² The velocity vector is given by V = (r`) Er + (r×𝜃`) E𝜃     = 4.608 Er +4.46×1.675 E𝜃     = 4.608 Er + 7.47 E𝜃 Where Er - radial unit vector               E𝜃 -  angular unit vector Also acceleration vector is given by A = (r``- r𝜃`²)Er + (2r

Hello programmers, Here are the 10 basic algorithms of programming which will help you to start to learn Algorithms and programming. What are Algorithms?? Algorithms are the set of instructions or protocols which tells us what should be the next step of the process or program. What are the Flowcharts?? Flowcharts are the diagramatic representation of steps involved in the code. Flowcharts shows the path followed by data during the process or iteration. Now following are the algorithms and their Flowcharts: 1) Algorithm for area of circle : 1.START 2.READ: The radius as "R" and area as "A" 3.INPUT: Get R and A from user 4.CAALCULATE: area  4.1 A=3.14*R*R 5.PRINT: "The area of circle of circle"+A 6.STOP Flowchart for area of circle : 2) Algorithm for factorial of 1 to 5  numbers : 1.START 2.READ: The number as "N" and factorial as "fact" 3.INPUT: Get "N" from user 4.Set the initial value of N a
