<u><em>The answer is . . . 786.8 N</em></u> (see work attached)
normal force = (mg)cos(θ) = (82kg)(9.81 m/s²)cos(12⁰) = 786.8 N
Answer:
Weight of the woman in Newton
Mass of the woman in slug
Mass of the woman in kg
My weight in Newton
Explanation:
From the question we are told that
The weight of the woman in pounds is
Converting to Newton
1 N = 0.22472 lb
x N = 157
=>
=>
Obtaining the mass in slug
Here
So
Obtaining the mass in kilogram
Here
So
Generally weight is mathematically represented as
Given that my mass is 80 kg then my weight is
The first answer should be correct if not then the second one
Answer
given,
mass of the solid door = 22 Kg
dimension of door = 220 cm x 91 cm
moment of inertia about the hinge
r is the distance from the one edge which is equal to 91 cm or 0.91 m
Moment of inertia about center for rectangular gate is equal to
moment of inertia for rotation about a vertical axis inside the door, 15 cm from one edge
