Abstract:
A method of making a load-indicating member comprising the steps of:providing a load-bearing member subjected to deformation when stressed such that one portion thereof moves relative to another portion thereof, said load-bearing member having a first end, a second end, and a predetermined length;contouring at least a portion of at least one of said first and second ends of said load-bearing member to reduce the influence of geometric variations and asymmetrical stress in said load-bearing member on ultrasonic measurement, said contour approximating a sphere and having a radius of curvature of approximately 25 to 70 percent of the length of said member; andproviding means for transmitting ultrasonic waves through said load-bearing member and receiving ultrasonic echoes, said ultrasonic wave transmitting and receiving means disposed at an end of said load-bearing member.
