Question

define pressure .explain why shoulder bags are provided with broad straps and not thin straps

Answer 1

pressure is a term which may be defined as force acting per unit area
formula is....
P = F/A
which means pressure is directly proportional to force and inversely proportional to area
now shoulder bags are provided with broad straps and not thin straps because when the straps are made broad the area of straps increases and hence the pressure on a shoulder decreases which prevent us from pain

Answer 2

pressure is defined as force per unit area. it's si unit is pascal
as we know that higher the area lesser the pressure so to reduce pressure bags have wider straps
