Question

A rod of XY of weight 16N is hinged at X and supported by a string at Y. The string is at angle 30°. The tension in the string is 16N.

What is the horizontal component of the force acting at X?
(A) 8N
(B) 9N
(C) 14N
(D) 16N

Answer 1

Answer:

Option C) 14N

Explanation:

we know that

To find out the horizontal component of the force acting at X, multiply the tension in the string by the cosine of 30 degrees

so

$(16\ N)cos(30^o)=13.9\ N$

Round to the nearest whole number

$14\ N$
