Resolution and Composition of Forces – Problem 2 – Engineering Mechanics

August 24, 2019


We will start with question number 2 question number 2 Let us read what is given the following forces act at a point number 1 20 Newton inclined at 30 degree towards Northeast second 25 Newton towards north 30 Newton towards North East and 35 Newton inclined at 40 degree southwest . Find the magnitude and direction of resultant force so here we would be calculating what is the magnitude value of resultant and direction of resultant so let us start with the question here I will be writing the data first given data in that we have 20 Newton force inclined at 30 degree towards north east

  1. here u said that southwest is west of south and u made 40degree towards west …and in northeast it means east of North so u should made 30degree from y axis towards x axis but u did opposite..???????

  2. Sir before u tell towards north-west means arrow mark u r taken downwards … and again u taking sometimes upwards

  3. Please please please please please please please please please please please please please please please please please send ra fast

  4. The all answers come to be wrong for summation fx it is -26.38 for summation fy it is 29.4 resultant is 39.50 and theta is 48.09

  5. Hai sir i am from andhra pradesh ur mechanics peoblems r very useful to me & good proper english keep it up sir

  6. You have done wrong in sum of all vertical forces
    Instead of (sin) you have taken (cos) …

  7. towards means,the direction of force(i.e;the arrow)should be towards x-axis. But,you have represented it in opposite order. Please,clear my doubt.

  8. Sir ans brabr hai. Lekin aapne fx me. -35cos(40). Ki jagah. -35sin(40). Likh diya hai esiliye bohat logo ko smaj nhi aarha

  9. Sir u done wrong …..in South of West u take vertical force is sin theta but all vertical force should be take only cos theta….

  10. O bhai jara khud ka banaya huaa video khud dekh liya karo
    Students are going wrong by your wrong solving
    Shameful 😏
