f a vehicle weighs 100 000 Newtons. What is the FORCE exerted on the road by one tire if it is a four- wheeled vehicle and the weight is evenly distributed?

Asatellite component is in the shape of a cube with 10cm edges, has an evenly distributed mass of 2 kg and one bolt hole at each of four corners. if the maximum predicted random vibration environment is 10 grms, what bolt size would be a good choice for restraint? what other factors might drive bolt size besides force/stress?
