Find the tension t in each cable and the magnitude and direction of the force exerted on the strut by the pivot in each of the arrangements in fig. 11.13. in each case let w be the weight of the suspended crate full of priceless art objects. the strut is uniform and also has weight w. start each case with a free body diagram of the strut. a) t=2.6w, 3.28w, 37.6 degreesb) t=4.1w, 5.39w, 48.8 degrees

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
