Answer:
The load weight is 2.29 N
Step-by-step explanation:
We note that at equilibrium, the sum of the moment and the sum of forces about a point is zero, therefore, we have;
∑M =0
∑F = 0
The parameters given are;
The distance of the load from the hinge = 35 cm
The distance of the load from the spring balance = 15 cm
The applied force on the spring balance = 4 N↑
The direction of the applied force on the spring balance = Upwards
Let the weight of the load = W↓
The direction of the weight of the load = Downwards
We use downward negative and upward positive coefficients for the forces
We take moment about the hinge as follows;
Sum of moments equals zero gives;
4 × (35 - 15) - W × 35 = 0
∴ 4 × (35 - 15) = W × 35
4 × 20 = W × 35
W = 4 × 20/35 = 2.29 N
The weight of the load = 2.29 N.
Answer:
0.65
Step-by-step explanation:
Just divide 13 by 20
Answer:
3 , 4 , 5 can formed right triangle
Step-by-step explanation:
In any triangle if the sum of the squares of the smallest two sides equals the square of the third side, then the triangle is right triangle
∵ 16² + 32² = 1280
∵ 36² = 1296 ≠ 1280 ⇒ Not right Δ
∵ 3² + 4² = 25
∵ 5² = 25 ⇒ right Δ
∵ 8² + 12² = 208
∵ 16² = 256 ≠ 208 ⇒ Not right Δ
∵ 9² + 10² = 181
∵ 11² = 121 ≠ 181 ⇒ Not right Δ
If you are rounding to the nearest tenth
Let's say round 20.15 to the nearest tenth. 1 is the tenth place. You have to look at the hundredths place. Since it is 5 and over You round up. If it is under 4 then you round down to it would be 20.2
