  1. Question 1

    Q1. An engineer applies a force of 100 N to a structural beam at an angle of 60 degrees with the horizontal axis. What is the horizontal component?

    • A) 86.6 N
    • B) 50.0 N
    • C) 100.0 N
    • D) 25.0 N

    Answer: 50.0 N

    Explanation: Fx equals F cos(theta), giving 100 cos(60) which is 50N. Option C fails because it uses the sine function incorrectly for horizontal components.
